1. DESCRIPTION
1.1. Overview
The 92HD73E is a high fidelity, 10-channel audio codec compatible with the Intel High Definition
(HD) Audio Interface. The 92HD73E codec provides high quality, HD Audio capability to desktop
and multi-media notebook.
The 92HD73E is designed to meet or exceed premium logo requirements for Microsoft’s Windows
Logo Program (WLP) 3.09 and revisions 4 as indicated in WLP 3.09.
The 92HD73E provides stereo 24-bit, full duplex resolution supporting sample rates up to 192kHz by
the DAC and ADC. 92HD73E SPDIF outputs support sample rates of 192kHz, 176.4kHz, 96kHz,
88.2kHz, 48kHz, and 44.1kHz. 92HD73E SPDIF input supports sample rates of 96kHz, 88.2kHz,
48kHz, and 44.1kHz. Additional sample rates are supported by the driver software.
The 92HD73E supports a wide range of desktop and consumer 8/10 channel configurations. The 2
independent SPDIF output interfaces provides connectivity to Consumer Electronic equipment like
Dolby Digital decoders, powered speakers, mini disk drives or to a home entertainment system.
Simultaneous HDMI and SPDIF output is possible.
MIC inputs can be programmed with 0/10/20/30dB boost. For more advanced configurations, the
92HD73E has 8 General Purpose I/O (GPIO).
The port presence detect capabilities allow the codecs to detect when audio devices are connected
to the codec. Load impedance sensing helps identify attached peripherals for easy set-up and a bet-
ter user experience. The fully parametric IDT SoftEQ can be initiated upon headphone jack insertion
and removal for protection of notebook speakers.
The 92HD73E operates with a 3.3V digital supply and either 3.3V, or 5V analog supply. It can also
work with 1.5V and 3.3V HDA signaling; the correct signalling level is selected dynamically based on
the power supply voltage on the DVDD-IO pin.
The 92HD73E is available in a 48-pin LQFP Environmental (ROHS) package.
Additional products with the same features as the 92HD73E are the 6-channel 92HD73C and the
8-channel 92HD73D.

1.4. Detailed Description
1.4.1. Port Functionality
Multi-function (Input / output) ports allow for the highest possible flexibility. 8 bi-directional ports (3
headphone capable) support a wide variety of consumer desktop and mobile system use models.
Note1: 40dB boost requires using the IDT driver. When the 40dB mic boost feature is enabled, addi-
tional gain increases greater than 6dB may result in significant audio quality degradation of the
microphone audio input. In particular, when the 40dB MIC boost is active, the SNR, THD+N and DC
offset will significantly degrade regardless of the input signal level.
1.4.2. Port Characteristics
Universal (Bi-directional) jacks are supported on all ports except the CD input. Ports A, B, and D are
designed to drive a set of 32 ohm (nominal) headphones or a 10K (nominal) load with on board
shunt resistance as low as 20K ohms (typical - used to maintain coupling CAP bias.) Line Level out-
puts are intended to drive an external 10K speaker load (nominal) and an on board shunt resistor of
20K-47K (nominal). However, applications may support load impedances of 5K ohms and above.
Input ports are 47K (nominal) at the pin.
DAC full scale output and intended full scale input levels are 1V rms. Line output ports and Head-
phone output ports on 92HD73E may be configured for +3dBV full scale output levels by using a
vendor specific verb.
Output ports are always on to prevent pops/clicks associated with charging and discharging output
coupling capacitors. This maintains proper bias on output coupling caps even in D3 as long as AVDD
is available. Unused ports should be left unconnected. When updating existing designs to use the
92HD73E, ensure that there are no conflicts between the output ports on 92HD73E and existing cir-
cuitry.

1.4.3. Jack Detect
Plugs inserted to a jack on Ports A, B, C, & D are detected using SENSE_A. Plugs inserted to a jack
on Ports E, F, G, and H are detected using SENSE_B. The following table summarizes the proper
resistor tolerances for different analog supply voltages.
SENSE_C, is different from SENSE_A and SENSE_B. Because SENSE_C only determines the
presence of a plug for the CD port (port I), SENSE_C is a simple digital input pin referenced to the
analog supply. An internal pull-up resistor is provided. No external resistors are needed (jack switch
shorts to ground when a plug is inserted.) If external components are added, or if the pin is driven by
a logic gate, care should be taken to ensure that the pin voltage is above 70% of AVDD when no
plug is in the jack and less than 30% AVDD when a plug is inserted.
See reference design for more information on Jack Detect implementation.
1.4.4. SPDIF Output
All SPDIF Outputs can operate at 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4KHz, and 192KHz as
defined in the Intel High Definition Audio Specification with resolutions up to 24 bits. This insures
compatibility with all consumer audio gear and allows for convenient integration into home theater
systems and media center PCs.
A second independant SPDIF Output is provided as an option for WLP compliant HDMI and SPDIF
outputs. Its function is identical to the primary SPDIF output.

Note: Peak to peak jitter is currently limited to less than 4.5nS (half of the internal master clock cycle)
which does not meet the IEC-60958-3 0.05UI requirement at 192KHz.
The two SPDIF ouput converters can not be aligned in phase with the DACs. Even when attached to
the same stream, the two SPDIF output converters may be misaligned with respect to their frame
boundaries.

1.4.5. SPDIF Input
SPDIF IN can operate at 44.1 KHz, 48 KHz, 88.2 KHz or 96 KHz, and implements internal Jack
Sensing.
A sophisticated digital PLL allows automatic rate detection and accurate data recovery. The ability to
directly accept consumer SPDIF voltage levels eliminates the need for costly external receiver ICs.
Advanced features such as record-slot-select and SPDIF_IN routing to the DAC allow for simulta-
neous record and play.
1.4.6. Analog Mixer
An analog mixer is available on the 92HD73E. The mixer supports independent gain (-34.5 to
+12dB in 1.5dB steps) on each input as well as independent mutes on each input. A master volume
follows mixing and provides gain from -46.5dB to 0dB in 1.5dB steps.
The following inputs are available:
•CD
• Analog PC_Beep
• Inport0_Mux
• Inport1_Mux
• Inport2_Mux

1.4.7. Input Multiplexers
92HD73E implements 4 port input multiplexers. These multiplexers allow a preselection of one of
four possible inputs:
1.4.8. ADC Multiplexers
92HD73E implements 2 ADC input multiplexers. These multiplexers incorporate the ADC record
gain function (0 to +22.5dB gain in 1.5dB steps) as an output amp and allow a preselection of one of
12 possible inputs:
•DMIC 0
•DMIC 1
• Mixer output
• CD input
•Ports A - H
1.4.9. Power Management
The HD Audio specification defines power states, power state widgets, and power state verbs.
Power management is implemented at several levels. The Audio Function Group (AFG) and all con-
verter widgets support the power state verb F05/705 (as well as the pin widget associated with pin
47.) Converter widgets are active in D0 and inactive in D1-D3.
The following table describes what functionality is active in each power state supported by the AFG.

1.4.9.1. AFG D0
The AFG D0 state is the active state for the device. All functions are active if their power state (if they
support power management at their node level) has been set to D0.
1.4.9.2. AFG D1
D1 is a lower power mode where all converter widgets are disabled. Analog mixer and port functions
are active.
1.4.9.3. AFG D2
The D2 state further reduces power by disabling the mixer and port functions. The port amplifiers
and internal references remain active to keep port coupling caps charged and the system ready for a
quick resume to either the D1 or D0 state.
1.4.9.4. AFG D3
The D3-default state is available for HD Audio compliance. All converters are shut down. Port ampli-
fiers and references are active but in a low power state to prevent pops. Resume times may be
longer than those from D2, but still very fast to meet Intel low power goals.
The traditional use for D3 was as a transitional state before power was removed (D3 cold) before the
system entered into standby, hibernate, or shut-down. To conserve power, Intel now promotes using
D3 whenever there are no active streams or other activity that requires the part to consume full
power. The system remains in S0 during this time. When a stream request or user activity requires

the CODEC to become active, the driver will immediately transition the CODEC from D3 to D0. To
enable this use model, the CODEC must resume within 10mS and not pop.
The default power state for the Audio Function Group after reset is D3-default
1.4.9.5. AFG D3 and vendor specific verbs
The programmable values, exposed via vendor-specific settings, are under the IDT Device Driver
control for further power reduction.
1.4.10. Low-voltage HDA Signaling
The 92HD73E is compatible with either 1.5V or 3.3V HDA bus signaling; the voltage selection is
done dynamically based on the input voltage of DVDD_IO.
When in 1.5V mode, the 92HD73E can correctly decode BITCLK, SYNC, RESET# and SDO as they
operate at 1.5V; additionally it will drive SDI and SDO at 1.5V. None of the GPIOs are affected, as
they always function at their nominal voltage (DVDD or AVDD).
1.4.11. Multi-channel capture
The capability to assign multiple ADC “Input Converters” to the same stream is supported to meet
the microphone array requirements of Vista and future operating systems. Single converter streams
are still supported and is done by assigning unique non zero Stream IDs to each converter. All cap-
ture devices (ADCs 0 and 1) may be used to create a multi-channel input stream. There are no
restrictions regarding digital microphones. However, the SPDIF input can not be used with an ADC
to create a 4-channel stream. SPDIF_In only supports stereo capture.
The ADC Converters can be associated with a single stream as long as the sample rate and the bits
per sample are the same. The assignment of converter to channel is done using the “CnvtrID” widget
and is restricted to even values. The ADC converters will always put out a stereo sample and there-
fore require 2 channels per converter.
The stream will not be generated unless all entries for the targeted converters are set identically, and
the total number of assigned converter channels matches the value in the NmbrChan field. These
are listed the “Multi-Converter Stream Critical Entries” table.
An example of a 4 Channel Steam with ADC0 supplying channels 0&1 and ADC1 supplying chan-
nels 2&3 is shown below. A 4 Channel stream can be created by assigning the same non-zero
stream id “Strm= N” to both ADC0 and ADC1. The sample rates must be set the same and the num-
ber of channels must be set to 4 channels “NmbrChan = 0011”.

1.4.12. EAPD
The EAPD pin (pin 47) also supports SPDIF_In and GPIO functions. The pin defaults to EAPD after
power on reset and will remain in EAPD mode until either GPIO is enabled for pin 47 or the port I/O
is enabled to support SPDIF. Although named External Amplifier Power Down (EAPD) by the HD
Audio specification, this pin operates as an external amplifier power up signal. The EAPD value is
reflected on the EAPD pin; a 1 causes the external amplifier to power up, and a 0 causes it to power
down. When the EAPD value = 1, the EAPD pin must be placed in a state appropriate to the current
power state of the associated Pin Widget even though the EAPD value may remain 1. The default
state of this pin is 0 (driving low) and a Pull-down prevents the line from floating high when the part is
in reset.

1.4.13. Digital Microphone Support
The digital microphone interface permits connection of a digital microphone(s) to the CODEC via the
DMIC0, DMIC1, and DMIC_CLK 3-pin interface. The DMIC0 and DMIC1 signals are inputs that carry
individual channels of digital Mic data to the ADC. In the event that a single microphone is used, the
data is ported to both ADC channels.
The DMIC_CLK output is controllable from 4.704Mhz, 3.528Mhz, 2.352Mhz, 1.176Mhz and is syn-
chronous to the 24Mhz internal clock. The default frequency is 2.352Mhz.
The two DMIC data inputs are reported as two stereo input pin widgets that incorporate a boost
amplifier. The pin widgets are shown connected to the ADCs through the same multiplexors as the
analog ports. Although the internal implementation is different between the analog ports and the dig-
ital microphones, the functionality is the same. In most cases, the default values for the DMIC clock
rate and data sample phase will be appropriate and an audio driver will be able to configure and use
the digital microphones exactly like an analog microphone.

1.4.14. PC-Beep
92HD73E supports both analog and digital PC_Beep functions.
1.4.14.1. Analog PC-Beep
92HD73E does not support automatic routing of the PC_Beep pin to all outputs when the link is in
reset. Analog PC-Beep may be supported during Link Reset if the mixer is manually configured for
pass-thru. Otherwise, Reset# must be high and Bit_Clk active.
The default values for the vendor specific verb (7EE/FEE in AFG) associated with Analog PC-Beep
are:
• Enable = 0h (Analog PC-Beep disabled - mute)
• volume = 3h (0dB)
Analog PC-Beep is supported in D3, but may be attenuated or distorted depending on the load-
impedance on the port. Line outputs can drive 10K ohm loads in D3 at 1Vrms, but will be current lim-
ited when driving lower impedance loads. Enabling or disabling analog PC-Beep may cause a click
or pop sound.
1.4.14.2. Digital PC-Beep
This block uses an 8-bit divider value to generate the PC beep from the 48kHz Azalia sync pulse.
The digital PC_Beep block generates the beep tone on all Pin Complexes that are currently config-
ured as outputs. The HD Audio spec states that the beep tone frequency = (48kHz HD Audio SYNC
rate) / (4*Divider), producing tones from 47 Hz to 12 kHz (logarithmic scale). Other audio sources
are disabled when digital PC_Beep is active.
It should be noted that digital PC Beep is disabled if the divider = 00h.
1.4.15. Headphone Drivers
This product implements a +3dBV output option on headphone capable ports. (HP output and line
output levels are defined as 1Vrms at this time with an option to enable +3dBV FSOV using a vendor
specific verb.) The Microsoft Windows Logo Program allows up to the equivalent of 100ohms in
series. However, an output level of +3dBV at the pin is required to support 300mV at the jack with a
32ohm load and 1V with a 320 ohm load. Microsoft allows device and system manufactures to limit
output voltages to address EU safety requirements. (WLP 3.09 - please refer to the latest Windows
Logo Program requirements from Microsoft.) 92HD73E, however, requires external components
(series resistors) to limit the output voltage to 150mV with a 32 ohm load or secure software limiting
by restricting DAC and mixer gain ranges.
Although 3 Headphone amplifiers are present, only two may be used simultaneously.
Performance will degrade when driving more than one set of headphones. Only one set of head-
phones (32 ohm nominal) may be connected to a headphone capable port.

1.4.16.1. GPIO Pin mapping and shared functions.
1.4.16.2. Volume/Digital Microphone/GPIO Selection
There are 3 functions available on pins 2 and 4. To determine which function is actually enabled on
the 2 pins, the order of precedence is followed:
1. If the GPIOs are enabled, they override both Volume Control and Digital Mics
2. If the GPIOs are not enabled through the AFG, then at reset, the Volume control is enabled with
the weak pull-up.
3. If BIOS or other software application enables either Digital Microphones inputs through the Con-
figuration Default Register, the Volume is disconnected and the pull-ups are disconnected with
the weak pull-downs enabled.
1.4.16.3. VRefOut/GPIO Selection
Two functions are available on pins 29, 31, and 37. To determine which function is actually enabled,
the order of precedence is followed:
1. If the GPIOx function is enabled, it overrides VRefOut-X
2. If the GPIO function is not enabled through the AFG, then the VrefOut function is enabled and in
its default state.
3. If using a VrefOut pin as GPIO, make sure to incorporate a 10K ohm external pull-up to AVDD to
prevent the pin from floating in GPI mode and to allow proper operation in open-drain GPO
mode.

1.4.17. External Volume Control
92HD73E incorporates a 2-pin volume control interface. Volume up, down, and mute functions are
easily implemented using 2 push-button switches. The CODEC provides internal pull-up resistors
simplifying external CODEC circuitry. Also, repeat and direct modes of operation add flexibility to the
interface. The typical usage model is for front panel master volume buttons on an entertainment PC,
or case mounted hardware volume control for mobile platforms.
1.4.17.1. Theory of Operation
The codec monitors the volume up/down inputs for a change of state from high to low, and waits for
the inputs to settle. If the inputs have not settled by the end of the de-bounce period, then the value
at the end of the period is used. A 0 (low voltage) on the Down pin will decrement the volume regis-
ter, while a 0 on the Up pin will increment the volume register. If both inputs are 0 at the same time,
then the volume register will be set to its lowest value (mute). Pressing Up, Down, or both buttons at
the same time when the volume control interface is in mute mode, will cause the part to un-mute.
The de-bounce / repeat rate is selectable from 2.5Hz to 20Hz in 2.5Hz increments using the Volume
Knob VCSR0 verb (FE0) Rate bits (bits 2:0). This value is used for both de-bounce and repeat rates.
The de-bounce period is the time that the CODEC waits for the inputs to settle, and the repeat rate is
the rate at which the CODEC will increment/decrement the volume if a volume button is pushed and
held. When a falling edge is detected on either one of the volume control pins, the codec will wait for
(1/Rate) seconds for the input to settle. If the Continuous bit is set in the Volume Knob VCSR0 verb
(bit 3), then the codec will wait for the de-bounce period to expire then repeatedly increment or dec-
rement the volume register at the rate specified in the Rate bits until the button is released.
1.4.17.2. Modes of Operation
•DIRECT MODE
In Direct mode, the Volume Knob widget directly controls the volume of all of the DACs in the part.
The volume in the Volume Knob widget acts as the master volume and limits the maximum volume
for each of the DAC amplifiers. The amp gain for each of the DACs can also be adjusted using the
DAC amplifiers. However, the actual gain for an individual DAC will be the sum of the Volume Knob
volume and the DAC amplifier volume. For example, if the DAC amplifier gain is set to 0x7F (0dB)
and the Volume Knob volume is set to 0x3F (-48dB) the resulting gain would be -48dB. If the combi-
nation of gains is less than -95.25dB (the equivalent to a value of 0x0 for the DAC or Volume Knob
volume settings) then the actual gain will be -95.25dB. For example, if the Volume Knob is set to
0x3F (-48dB) and the DAC amplifier volume is set to 0x1F (-72dB) then the DAC volume will be set
to -95.25dB.
Direct mode is enabled by setting bit 7 in the Volume Knob Cntrl verb (F0F). The volume is reflected
in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode, software can read or
write the volume in the Volume Knob widget.
• INDIRECT MODE
In indirect mode, the Volume Knob widget does not directly control the DAC amplifier gains. An
event on the volume Up/Down pins will increment/decrement the value in the Volume Knob Cntrl
verb (F0F) volume bits (bits 6:0) just as in Direct mode. However, instead of adjusting the DAC
amplifier gain, an unsolicited response is generated (if enabled) and the control software must read

the volume in the Volume Knob widget and take appropriate action. Indirect mode is particularly use-
ful when it is undesirable to control all of the DAC amplifier volumes at the same time, or when imple-
menting ADC volume control.
In indirect mode, there are only 128 volume levels in the Volume Knob Cntrl volume bits, the value
will not go beyond the lower and upper limits (0x0 or 0x7F), and an unsolicited response will be gen-
erated if an input event tries to go beyond these limits. Therefore, it is the responsibility of the con-
trolling software to monitor the volume in the Volume Knob Widget and take appropriate action.
Indirect mode is enabled by clearing bit 7 in the Volume Knob Cntrl verb (F0F). The volume is
reflected in the Volume Knob Cntrl bits 6:0 and the step size is 0.75dB. In direct mode, software can
read or write the volume in the Volume Knob widget.
1.4.17.3. Hardware Implementation
The Volume Knob interface is comprised of two input pins, CODEC pins 2 and 4. Both pins have
internal pull-up resistors, so only two push button switches are required for most implementations.
Typically, a series resistor and shunt capacitor are used to help reduce noise and prevent damage
from ESD and other potential faults. An example circuit is shown below in below.

2.2. 92HD73E 5V, 4.75V, and 3.3V Analog Performance Characteristics
(Tambient = 25 ºC, AVdd = Supply ± 5%, DVdd = 3.3V ± 5%, AVss=DVss=0V; 20Hz to 20KHz swept
sinusoidal input; Sample Frequency = 48 kHz; 0 dB = 1 VRMS, 10KΩ//50pF load, Testbench Char-
acterization BW: 20 Hz – 20 kHz, 0 dB settings on all gain stages)
ESD: The 92HD73E is an ESD (electrostatic discharge) sensitive device. The human body and test equipment can
accumulate and discharge electrostatic charges up to 4000 Volts without detection. Even though the 92HD73E implements
internal ESD protection circuitry, proper ESD precautions should be followed to avoid damaging the functionality or
performance.

1.Dynamic Range is the ratio of the full scale signal to the noise output with a -60dBFS signal as defined in AES17 as SNR in the
presence of signal and outlined in AES6id, measured “A weighted” over 20 Hz to 20 kHz bandwidth
2.Ratio of Full Scale signal to idle channel noise output is measured “A weighted” over a 20 Hz to a 20 kHz bandwidth.
(AES17-1991 Idle Channel Noise or EIAJ CP-307 Signal-to-noise Ratio).
3.THD+N ratio as defined in AES17 and outlined in AES6id,non-weighted, over 20 Hz to 20 kHz bandwidth.Results at the jack
are dependent on external components and will likely be 1 - 2dB worse.
4.Peak-to-Peak Ripple over Passband meets ± 0.125dB limits, 48 kHz or 44.1 kHz Sample Frequency. 1dB limit.
5.Stop Band rejection determines filter requirements. Out-of-Band rejection determines audible noise.
6.The integrated Out-of-Band noise generated by the DAC process, during normal PCM audio playback, over a bandwidth 28.8
to 100 kHz, with respect to a 1 Vrms DAC output.
7.Gain drift is the change in analog volume control gain for each step across the supported 0 oC TO 70 oC temperature range
referenced to the 25 oC gain value and specified in ppm per oC
8.± 1dB limits for Line Output & 0 dB gain, at -20dBV
9.Spurious tone rejection is tested with ADC dither enabled and compared to ADC performance without dither.

5.2. Pin Configuration Default Register Settings
The configuration default registers are 32-bit registers required for each pin widget. These registers are normally used
by the CODEC driver to determine the configuration of jacks and devices attached to the CODEC. When the CODEC is
powered on, these registers are loaded with the default values provided by IDT for typical system usage, and are
loaded in a way that is compatible with the Microsoft Universal Audio Architecture (UAA) driver. The values can be
overridden by IDT customers according to their system configuration. Table shows the Pin Widget Configuration
Default settings.
The settings reflect the Consumer Desktop use model with:
•Independent Front Headphone and Microphone for real time communication
•7.1 audio output at the rear
•Rear Microphone and Line Input jacks
•Optical SPDIF input and output jacks at the rear
•HDMI
•Digital Microphones are connected as a 4-mic array (Volume Knob Widget is visible, but inactive)
•Analog CD input is connected to an internal ATAPI connector.

6. WIDGET INFORMATION
There are two types of responses: Solicited and Unsolicited. Solicited responses are provided as a
direct response to an issued command and will be provided in the frame immediately following the
command. Unsolicited responses are provided by the CODEC independent of any command. Unso-
licited responses are the result of CODEC events such as a jack insertion detection. The formats for
Solicited Responses and Unsolicited Responses are shown in the tables below. The “Tag” field in
bits [31:28] of the Unsolicited Response identify the event.

[7.:0] Divider RW 00 Enable internal PC-Beep generation.
Divider == 00h disables internal PC
Beep generation and enables normal
operation of the codec. Divider != 00h
generates the beep tone on all Pin Com-
plexes that are currently configured as
outputs. The HD Audio spec states that
the beep tone frequency = (48kHz HD
Audio SYNC rate) / (4*Divider), produc-
ing tones from 47 Hz to 12 kHz (logarith-
mic scale). This part can selectively
generate tones with frequency = 48KHz
* (257 - Divider) / 1024, yielding a linear
range from 12kHz to 93.75Hz in steps of
46.875Hz. If the FreqShift bit is set, then
the beep tones generated have frequen-
cy = 48KHz * (513 - Divider) / 1024,
yielding a range of 24kHz to
12093.75Hz in steps of 46.875Hz.
