This multiformat 3D comb filter decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of a composite or an S-Video input signal into a HDMI output stream. SCART and overlay functionality are enabled by the ability of the ADV7850 to process CVBS and standard definition RGB signals simultaneously. The ADV7850 contains one main component processor (CP) that processes YPrPb and RGB component formats, including RGB graphics. The ADV7850 can operate in quad HDMI and analog input mode, thus allowing for fast switching between the analog video inputs and HDMI. The ADV7850 supports the decoding of a component RGB/ YPrPb video signal into a HDMI output stream. The support for component video includes 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and 1250i standards, as well as many other SMPTE and HD standards. The ADV7850 supports graphics digitization. The ADV7850 is capable of digitizing RGB graphics signals from VGA to UXGA rates and converting them into an HDMI output stream. Internal EDID RAM is available for one graphics port. The ADV7850 incorporates a quad input HDMI-compatible receiver that supports all HDTV formats up to 3D 1080p 60 Hz and 2160P 24 Hz. The ADV7850 supports full HDCP decryption with internal key storage. The ADV7850 features HDCP authentication on all ports simultaneously. The feature allows fast switching between HDMI ports. Sync measurements and status monitoring are also available for all HDMI ports. Each HDMI port has dedicated 5 V detect and hot plug assert pins. The HDMI receiver also includes an integrated equalizer that ensures robust operation of the interface with cable lengths up to 30 meters. The HDMI receiver has advanced audio functionality, such as a mute flag, that prevents audible extraneous noise in the audio output. In addition, the HDMI receiver incorporates internal EDID support, which can be made available in full power, powerdown, and power-off modes. An internal regulator supplies external EDID memory from the HDMI 5 V signal in poweroff mode. The ADV7850 incorporates XpressviewTM fast switching on all HDMI input ports. Using the Analog Devices, Inc., hardwarebased HDCP engine that minimizes software overhead, Xpressview technology allows fast switching between any two HDMI input ports in less than 1 second. The ADV7850 offers a flexible audio output port for the audio data decoded from the HDMI stream. HDMI audio formats, including super audio CD (SACD) via DSD, DST, and HBR are supported. The ADV7850 also features the single mode audio return channel (ARC) feature. ARC simplifies cabling by combining upstream audio capability in a conventional HDMI cable. The stereo audio ADC converts analog audio inputs and provides the data to the back end via the HDMI interface. The stereo audio DAC receives I2S data from the back end and converts it to analog audio output. The audio output is available as both high impedance and a driven output, which is suitable for driving headphones directly. Fabricated in an advanced CMOS process, the ADV7850 is provided in a 19 mm x 19 mm, 425-ball, CSP_BGA, surfacemount, RoHS-compliant package, and is specified over the -20C to +70C temperature range.

The most efficient measurement solution is obtained using the package surface temperature to estimate the die temperature because this eliminates the variance associated with the JA value. The maximum junction temperature (TJ MAX) of 125C must not be exceeded. The following equation calculates the junction temperature using the measured package surface temperature and applies only when no heat sink is used on the device under test (DUT): ( TJ = TS + JT x WTOTAL -0.3 V to +0.3 V ) where: TS is the package surface temperature (C).

POWER-DOWN SEQUENCE The ADV7850 supplies can be powered down simultaneously as long as the 3.3 V supply domain does not go below the 1.8 V supply domain. 3.3V SUPPLIES 1.8V Table 8 shows the current rating recommendations for power supply design. These values should be used when designing a power supply section to ensure that an adequate current can be supplied to the ADV7850. 1.8V SUPPLIES Table 8.

Building on the feature set of Analog Devices existing HDMI devices, the ADV7850 also offers support for all HDTV formats up to 3D 1080p at 60 Hz and 2160p at 24 Hz. Xpressview fast switching technology, using the Analog Devices hardware-based HDCP engine that minimizes software overhead, allows switching between any two input ports in less than 1 second. With the inclusion of HDCP 1.4, the ADV7850 can receive encrypted video content. The HDMI interface of the ADV7850 allows for authentication of a video receiver, decryption of encoded data at the receiver, and renewal of that authentication during transmission, as specified by the HDCP 1.4 protocol. Repeater support is also offered by the ADV7850. The ADV7850 supports the audio return channel feature. There is a dedicated S/PDIF input on which audio can be received for retransmission on the HDMI input. Wide ranges of 3D video formats are supported, including frame packing up to 3D 1080p at 60 Hz and 2160p at 24 Hz. The HDMI receiver incorporates active equalization of the HDMI data signals. This equalization compensates for the high frequency losses inherent in HDMI and DVI cabling, especially at longer lengths and higher frequencies. It is capable of equalizing for cable lengths up to 30 meters to achieve robust receiver performance at even the highest HDMI data rates. The HDMI receiver offers advanced audio functionality. It supports multichannel I2S audio for up to eight channels. It also supports a six-DSD channel interface with each channel carrying an oversampled 1-bit representation of the audio signal as delivered on SACD. The ADV7850 can also receive HBR audio packet streams and outputs them through the HBR interface in an S/PDIF format conforming to the IEC 60958 standard. * * ANALOG FRONT END The ADV7850 analog front end comprises four 170 MHz, 12-bit ADCs that digitize the analog video signal before applying it to the standard definition processor (SDP) or component processor (CP). The front end also includes a 13-channel input mux that enables multiple video signals to be applied to the ADV7850 without the requirement of an external mux. Current and voltage clamp control loops ensure that any dc offsets are set properly for the video signal. The clamps are positioned in front of each ADC to ensure that the video signal remains within the range of the converter. The ADCs are configured to run up to 4x oversampling mode when decoding composite, S-Video, or SCART inputs. For component 525i, 625i, 525p, and 625p sources, 4x oversampling is performed. Higher frequency video standards can be 2x or 1x oversampled. Oversampling the video signals reduces the cost and complexity of external antialiasing filters with the benefit of an increased signal-to-noise ratio (SNR). Optional internal antialiasing filters with programmable bandwidth are positioned in front of each ADC. These filters can be used to band-limit video signals, removing spurious outof-band noise. The ADV7850 can support the simultaneous processing of CVBS and RGB standard definition signals to enable SCART compatibility and overlay functionality. A combination of CVBS and RGB inputs can be mixed with the output under the control of I2C registers. Analog front-end features include: * The receiver contains an audio mute controller that can detect a variety of conditions that may result in audible extraneous noise in the audio output. On detection of these conditions, the audio signal can be muted to prevent audio clicks or pops. * HDMI receiver features include: * * * * * * * * * * 4:1 multiplexed HDMI receiver HDMI, ARC, and 3D format support, DVI 1.0 297 MHz HDMI receiver Integrated equalizer High-bandwidth Digital Content Protection (HDCP 1.4) on background ports Internal HDCP keys 36-/30-bit Deep Color support PCM, HBR, DSD, and DST audio packet support Repeater support Internal E-EDID RAM Hot plug assert output pin for each HDMI port * * * Rev. 0 | Page 25 of 32 Four 170 MHz, 12-bit NSV ADCs that enable 10-bit (SD)/ 12-bit (CP) video decoding 13-channel analog input mux that enables multiple source connections without the requirement of an external mux Four current and voltage clamp control loops that ensure any dc offsets are set properly for the video signal SCART functionality and SD RGB overlay on CVBS controlled by fastblank input SCART source switching detection through the TRI1 to TRI8 inputs Four programmable antialiasing filters ADV7850 Data Sheet * STANDARD DEFINITION PROCESSOR The SDP is capable of decoding a large selection of baseband video signals in composite, S-Video, and 525i/625i component formats. The video standards supported by the SDP include PAL, PAL 60, PAL M, PAL N, PAL NC, NTSC M/J, NTSC 4.43, and SECAM. The ADV7850 can automatically detect the video standard and process it accordingly. The SDP has a 3D temporal comb filter and a five-line adaptive 2D comb filter that gives superior chrominance and luminance separation when decoding a composite video signal. This highly adaptive filter automatically adjusts its processing mode according to the video standard and signal quality with no user intervention required. The SDP has an IF filter block that compensates for attenuation in the high frequency chroma spectrum due to a tuner SAW filter. The SDP has specific luminance and chrominance parameter controls for brightness, contrast, saturation, and hue. The ADV7850 implements a patented Adaptive Digital Line Length Tracking (ADLLTTM) algorithm to track varying video line lengths from sources such as a VCR. ADLLT enables the ADV7850 to track and decode poor quality video sources (such as VCRs) and noisy sources (such as tuner outputs, VCR players, and camcorders). Frame TBC ensures stable clock synchronization between the decoder and the downstream devices. The SDP also contains both a luma transient improvement (LTI) block and a chroma transient improvement (CTI) block. These increase the edge rate on the luma and chroma transitions, resulting in a sharper video image. The SDP has a Macrovision(R) detection circuit that allows Type I, Type II, and Type III Macrovision protection levels. The decoder is also fully robust to all Macrovision signal inputs. SDP features include: * * * * * * * * * * * Advanced adaptive 3D comb (using the external DDR2 memory) Adaptive 2D five-line comb filters for NTSC and PAL that give superior chrominance and luminance separation for composite video Full automatic detection and autoswitching of all worldwide standards (PAL, NTSC, and SECAM) Automatic gain control with white peak mode that ensures the video is always processed without loss of the video processing range Proprietary architecture for locking to weak, noisy, and unstable sources from VCRs and tuners IF filter block that compensates for high frequency luma attenuation due to tuner SAW filter LTI and CTI Vertical and horizontal programmable luma peaking filters 4x oversampling (54 MHz) for CVBS, and S-Video modes Free-run output mode that provides stable timing when no video input is present or video lock is lost Internal color bar test pattern * Advanced TBC with frame synchronization, which ensures nominal clock and data for nonstandard input Color controls that include hue, brightness, saturation, and contrast COMPONENT PROCESSOR The CP section of the ADV7850 is capable of decoding and digitizing a wide range of component video formats in any color space. Component video standards supported by the CP include 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, 1250i, VGA up to UXGA at 60 Hz, and many other standards. The any-to-any, 3 x 3 CSC matrix is placed between the analog front end and the CP section. This enables YPbPr-to-RGB and RGB-to-YCbCr conversions. Many other standards of color space can be implemented using the color space converter. The CP section contains circuitry to enable the detection of Macrovision encoded YPbPr signals for 525i, 625i, 525p, and 625p. It is designed to be fully robust when decoding these types of signals.

A 5:1 stereo mux is placed in front of the ADC input. The DAC output is available as a line level output and is passed through an internal headphone amplifier. The integrated headphone amplifier eliminates the need for an external amplifier when driving headphones. 2.8 V rms INPUT 22k 10.1k 2.8 V rms INPUT 22k 10.1k ANALOG AUDIO MUX FUNCTIONALITY A factory calibration is applied during final test to ensure that the gain through the mux circuit remains within 5%. Calibration is also applied to the ADC reference current to ensure that the code swing from the ADC remains within 5% across the part for a given input. External impedances with a tolerance of 1% are required. Figure 11. Audio Block The ADV7850 has five stereo analog audio inputs and one stereo analog output. Any one of the stereo inputs can be connected to the stereo ADC, and any one of the inputs can be connected to the stereo output. In the case of the analog output, the ADV7850 also supports mono in-stereo output. The I/O connectivity is shown in Table 9. Table 9.

Measured from the system audio input connector, the total nominal input impedance is 32.1 k. All analog system audio inputs are designed to support 2.8 V rms audio input. Figure 12 shows a high level overview of the implementation. The input level at the analog audio input pins on the ADV7850 is 880 mV rms. However, the ADV7850 incorporates a gain stage to restore the mux output level to 1.0 V rms. An external line driver is required to restore the audio output signals to the SCART specification of 2.8 V rms. Analog audio mux output signals are inverted with respect to mux input signals.

High Level Overview of Analog Audio Input/Output Configuration AUDIO CODEC FUNCTIONALITY The ADV7850 audio codec requires an external MCLK. For MCLK with a frequency of 6.144 MHz, 12.288 MHz, or 24.576 MHz, the ADC and DAC sample rate is 48 kHz. If the MCLK is reduced to 5.6448 MHz, 11.2896 MHz, or 22.5792 MHz, the ADC and DAC sample rate reduces to 44.1 kHz. The bandwidth of the digital filter is sufficient so that 20 kHz pass band is maintained in this mode. The 32 kHz sampling is also possible but with pass-band reduction. The system controller must set an I2C control to select the correct mode of operation for the internal PLL so that it always generates an internal MCLK of 6.144 MHz. A fixed oversample rate of 128x is implemented. The word depth of both the ADC and DAC is 24 bits. The ADC and DAC have independent LRCLK and SCLK signals but use a common MCLK. The ADC supports I2S mode, providing LRCLK, SCLK, and I2S signals. These signals are sent to the HDMI Tx and embedded into the HDMI stream. The DAC supports I2S mode. The LRCLK, SCLK, and data signals must be provided by the back-end SOC and must be frequency locked with the MCLK but can be phase independent. The output level is 1 V rms full scale. There is one stereo headphone amplifier output capable of driving 32 loads at 1 V rms. The headphone output incorporates circuitry to suppress pop/click sounds during power-on/off cycle.
