7 Detailed Description
7.1 Overview
The TFP401A-Q1 device is a digital visual interface (DVI)-compliant TMDS digital receiver used in digital flat-
panel display systems to receive and decode TMDS-encoded RGB pixel data streams. In a digital display
system, a host (usually a PC or workstation) contains a TMDS-compatible transmitter that receives 24-bit pixel
data along with appropriate control signals. The host encodes the data and control signals into a high-speed low-
voltage differential serial bit stream (fit for transmission over a twisted-pair cable) to a display device. The display
device (usually a flat-panel monitor) requires a TMDS-compatible receiver like the TI TFP401A-Q1 device to
decode the serial bit stream back to the same 24-bit pixel data and control signals that originated at the host.
This decoded data is then suitable for application directly to the flat-panel drive circuitry to produce an image on
the display. Host and display separation distances can be up to 5 meters or more, making serial transmission of
the pixel data preferable. Support of modern display resolutions up to UXGA requires a high-bandwidth receiver
with good jitter and skew tolerance.
7.2 Functional Block Diagram
7.3 Feature Description
7.3.1 TMDS Pixel Data and Control Signal Encoding
The device transmits only one of two possible transition-minimized differential signaling (TMDS) characters for a
given pixel at a given time. The transmitter keeps a running count of the number of ones and zeros previously
sent, and transmits the character that minimizes the number of transitions to approximate a dc balance of the
transmission line.
Reception of RGB pixel data during active display time uses three TMDS channels, DE = high. The same three
channels also receive control signals, HSYNC, VSYNC, and user-defined control signals CTL[3:1]. Reception of
these control signals occurs during inactive display or blanking-time. Blanking-time is when DE = low. The
following table maps the received input data to the appropriate TMDS input channel in a DVI-compliant system.

(1) Some TMDS transmitters transmit a CTL0 signal. The TFP401A-Q1 device decodes and transfers CTL[3:1] and ignores CTL0
characters. CTL0 is not available as a TFP401A-Q1 output.

The TFP401A-Q1 device discriminates between valid pixel TMDS characters and control TMDS characters to
determine the state of active display versus blanking, in effect, the state of DE.
7.3.2 TFP401A-Q1 Clocking and Data Synchronization
The TFP401A-Q1 device receives a clock reference from the DVI transmitter that has a period equal to the pixel
time, tpix. Another name for the frequency of this clock is the pixel rate. Because the TMDS encoded data on
Rx[2:0] contains 10 bits per 8-bit pixel, it follows that the Rx[2:0] serial bit rate is 10 times the pixel rate. For
example, the required pixel rate to support a UXGA resolution with 60-Hz refresh rate is 165 MHz. The TMDS
serial bit rate is 10× the pixel rate, or 1.65 Gb/s. Due to the transmission of this high-speed digital bit stream, on
three separate channels (or twisted-pair wires) of long distances (3–5 meters), there is no assurance of phase
synchronization between the data steams and the input reference clock. In addition, skew between the three data
channels is common. The TFP401A-Q1 device uses a oversampling scheme of the input data streams to
achieve reliable synchronization with up to 1-tpix channel-to-channel skew tolerance. Accumulated jitter on the
clock and data lines due to reflections and external noise sources is also typical of high-speed serial data
transmission; hence, the TFP401A-Q1 design for high jitter tolerance.
A phase-locked loop (PLL) conditions the input clock of the TFP401A-Q1 device to remove high-frequency jitter
from the clock. The PLL provides four 10× clock outputs of different phase to locate and sync the TMDS data
streams (4× oversampling). During active display, the pixel data encoding is for transition minimization, whereas
in blank, the control data encoding is for transition maximization. Transmitting in blank for a minimum period of
time, 128 tpix, requires a DVI-compliant transmitter to ensure sufficient time for data synchronization when the
receiver sees a transition-maximized code. Synchronization during blank, when the data is transition-maximized,
ensures reliable data-bit boundary detection. Phase synchronization to the data streams, maintained as long as
the link remains active, is unique for each of the three input channels.
7.3.3 TFP401A-Q1 TMDS Input Levels and Input Impedance Matching
The TMDS inputs to the TFP401A-Q1 receiver have a fixed single-ended termination to AVDD. A laser trim
process internally optimizes the TFP401A-Q1 device to fix the impedance precisely at 50 Ω. The device functions
normally with or without a resistor on the EXT_RES pin, so it remains drop-in compatible with current sockets.
The fixed impedance eliminates the need for an external resistor while providing optimum impedance matching
to standard 50-ΩDVI cables.
Figure 15 shows a conceptual schematic of a DVI transmitter and TFP401A-Q1 receiver connection. A
transmitter drives the twisted-pair cable through a current source, usually using an open-drain type of output
driver. The internal resistor, matched to the cable impedance at the TFP401A-Q1 input, provides a pullup to
AVDD. Naturally, with the transmitter disconnected and the TFP401A-Q1 DVI inputs left unconnected, the
TFP401A-Q1 receiver inputs pull up to AVDD.Figure 16 shows the single-ended differential signal and full-
differential signal. The design of the TFP401A-Q1 device is for response to differential signal swings ranging
from 150 mV to 1.56 V, with common-mode voltages ranging from (AVDD 300 mV) to (AVDD 37 mV).

7.3.4 TFP401A-Q1 Device Incorporates HSYNC Jitter Immunity
Several DVI transmitters available in the market introduce jitter on the transmitted HSYNC and VSYNC signals
during the TMDS encryption process. The HSYNC signal can shift by one pixel position (one clock) from nominal
in either direction, resulting in up to two cycles of HSYNC shift. This jitter carries through to the DVI receiver, and
if the position of HSYNC shifts continuously, the receiver can lose track of the input timing, causing pixel noise to
occur on the display. For this reason, one should use a DVI-compliant receiver with HSYNC jitter immunity in all
displays that could be connected to host PCs with transmitters that have this HSYNC jitter problem.
The TFP401A-Q1 integrates HSYNC regeneration circuitry that provides a seamless interface to these
noncompliant transmitters. The regeneration circuitry always fixes the position of the data enable (DE) signal in
relation to data, irrespective of the location of HSYNC. The TFP401A-Q1 receiver uses the DE and clock signals
to recreate stable vertical and horizontal sync signals. The circuit filters the HSYNC output of the receiver and
shifts HSYNC to the nearest eighth bit boundary, producing a stable output with respect to the data, as shown in
Figure 17. This ensures accurate data synchronization at the input of the display timing controller.
This HSYNC regeneration circuit is transparent to the monitor, and removal is unnecessary even if the
transmitted HSYNC is stable. For example, the PanelBus line of DVI 1.0-compliant transmitters, such as the
TFP6422 and TFP420, do not have the HSYNC jitter problem. The TFP401A-Q1 device operates correctly with
either compliant or noncompliant transmitters. In contrast, the TFP401A-Q1 device is ideal for customers who
have control over the transmit portion of the design, such as bundled-system manufacturers and for internal
monitor use (the DVI connection between monitor and panel modules).

7.4.2 TFP401A-Q1 Output Driver Configurations
The TFP401A-Q1 device provides flexibility by offering various output driver features for use to optimize power
consumption, ground bounce, and power-supply noise. The following sections outline the output driver features
and their effects.
Output Driver Power Down (PDO = low): Pulling PDO low places all the output drivers, except CTL1 and
SCDT, into a high-impedance state. One can tie the SCDT output, which indicates link-disabled or link-inactive,
directly to the PDO input to disable the output drivers when the link is inactive or when the cable is disconnected.
An internal pullup on the PDO pin defaults the TFP401A-Q1 device to the normal nonpower-down output-drive
mode if left unconnected.
Drive Strength (ST = high for high drive strength, ST = low for low drive strength): The TFP401A-Q1 device
allows for selectable output drive strength on the data, control, and ODCK outputs. See the DC Electrical
Characteristics table for the values of IOH and IOL current drives for a given ST state. The high output-drive
strength offers approximately two times the drive as the low output-drive strength.
Time-Staggered Pixel Output: This option works only in conjunction with the 2-pixels-per-clock mode (PIXS =
high). Setting STAG = low time-staggers the even- and odd-pixel outputs so as to reduce the amount of
instantaneous current surge from the power supply. Depending on the PCB layout and design, this can help
reduce the amount of system ground bounce and power-supply noise. The time stagger is such that in 2-pixels-
per-clock mode, the even pixel is delayed from the latching edge of ODCK by 0.25 tcip. (tcip is the period of
ODCK. The ODCK period is 2 tpix when in 2-pixels-per-clock mode.)

Depending on system constraints of output load, pixel rate, panel input architecture, and board cost, the
TFP401A-Q1 drive-strength and staggered-pixel options allow flexibility to reduce system power-supply noise,
ground bounce, and EMI.
Power Management: The TFP401A-Q1 device offers several system power-management features.
The output-driver power down (PDO = low) is an intermediate mode which offers several uses. During this mode,
all output drivers except SCDT and CTL1 go into a high-impedance state while the rest of the device circuitry
remains active.
Power down (PD = low) of the TFP401A-Q1 device is a complete power down in that it powers down the digital
core, the analog circuitry, and output drivers. All output drivers go into a Hi-Z state. Of all the inputs, only PD
remains active. The TFP401A-Q1 device does not respond to any digital or analog inputs until PD is pulled high.
Both PDO and PD have internal pullups, so if left unconnected they default the TFP401A-Q1 device to normal
operating modes.
Sync Detect: The TFP401A-Q1 device offers an output, SCDT, to indicate link activity. The TFP401A-Q1 device
monitors activity on DE to determine if the link is active. When 1 million (1e6) pixel clock periods pass without a
transition on DE, the TFP401A-Q1 device considers the link inactive, and drives SCDT low. While SCDT is low, if
two DE transitions are detected within 1600 pixel clock periods, the device considers the link active and pulls
SCDT high.
A use of SCDT is to signal a system power management circuit to initiate a system power down when the device
considers the link inactive. One can also tie the SCDT directly to the TFP401A-Q1 PDO input to power down the
output drivers when the link is inactive. It is not recommended to use SCDT to drive the PD input, because once
in complete power-down, the analog inputs are ignored and the SCDT state does not change. An external
system power-management circuit to drive PD is preferred.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TFP401A-Q1 is a DVI (Digital Visual Interface) compliant digital receiver that is used in digital flat panel
display systems to receive and decode T.M.D.S. encoded RGB pixel data streams. In a digital display system a
host, usually a PC or workstation, contains a DVI compliant transmitter that receives 24 bit pixel data along with
appropriate control signals and encodes them into a high speed low voltage differential serial bit stream fit for
transmission over a twisted-pair cable to a display device. The display device, usually a flat-panel monitor, will
require a DVI compliant receiver like the TI TFP401A-Q1 to decode the serial bit stream back to the same 24 bit
pixel data and control signals that originated at the host. This decoded data can then be applied directly to the
flat panel drive circuitry to produce an image on the display. Since the host and display can be separated by
distances up to 5 meters or more, serial transmission of the pixel data is preferred. The TFP401A-Q1 will support
resolutions up to UXGA.

9 Power Supply Recommendations
Use solid ground planes, tie ground planes together with as many vias as is practical. This will provide a
desirable return path for current. Each supply should be on separate split power planes, where each power plane
should be as large an area as possible. Connect PanelBus receiver power and ground pins and all bypass caps
to appropriate power or ground plane with via. Vias should be as fat and short as practical, the goal is to
minimize the inductance.
9.1 DVDD
Place one 0.01-uF capacitor as close as possible between each DVDD device pin (Pins 6, 38, 67) and ground.
9.2 OVDD
Place one 0.01-µF capacitor as close as possible between each OVDD device pin (Pins 18, 29, 43, 57, 78) and
ground.
A 22-µF tantalum capacitor should be placed between the supply and 0.01-uF capacitors.
A ferrite bead should be used between the source and the 22-uF capacitor.
9.3 AVDD
Place one 0.01-uF capacitor as close as possible between each AVDD device pin (Pins 82, 84, 88, 95) and
ground.
A 22-uF tantalum capacitor should be placed between the supply and 0.01-uF capacitors.
A ferrite bead should be used between the source and the 22-uF capacitor.
9.4 PVDD
Place three 0.01-µF capacitors in parallel as close as possible between the PVDD device pin (Pin 97) and
ground. A 22-µF tantalum capacitor should be placed between the supply and 0.01-µF capacitors. A ferrite bead
should be used between the source and the 22-uF capacitor.

10 Layout
10.1 Layout Guidelines
10.1.1 Layer Stack
The pinout of Texas Instruments High Speed Interface (HSI) devices features differential signal pairs and the
remaining signals comprise the supply rails, VCC and ground, and lower speed signals such as control pins. As
an example, consider a device X which is a repeater/re-driver, so both its inputs and outputs are high-speed
differential signals. These guidelines can be applied to other high-speed devices such as drivers, receivers,
multiplexers, and so on.
A minimum of four layers is required to accomplish a low EMI PCB design. Layer stacking should be in the
following order (top-to-bottom): high-speed differential signal layer, ground plane, power plane and control signal
layer.
Figure 24. Layer Stack
10.1.2 Routing High-Speed Differential Signal Traces (RxC-, RxC+, Rx0-, Rx0+, Rx1-, Rx1+, Rx2-, Rx2+)
Trace impedance should be controlled for optimal performance. Each differential pair should be equal in length
and symmetrical and should have equal impedance to ground with a trace separation of 2X to 4X Height. A
differential trace separation of 4X Height yields about 6% cross-talk (6% effect on impedance). We recommend
that differential trace routing should be side by side, though it is not important that the differential traces be tightly
coupled together because tight coupling is not achievable on PCB traces. Typical ratios on PCB’s are only 20-
50%, 99.9% is the value of a well-balanced twisted pair cable. Each differential trace should be as short as
possible (< 2 inches preferably) with no 90° angles. These high-speed transmission traces hould be on layer 1
(top layer).
RxC-, RxC+, Rx0-, Rx0+, Rx1-, Rx1+, Rx2-, Rx2+ signals all route directly from the DVI connector pins to the
device, no external components are needed.

10.3 TI PowerPAD 100-TQFP Package
The TFP401A-Q1 device comes in TI's thermally enhanced PowerPAD 100-TQFP package. The PowerPAD
package is a 14-mm × 14-mm × 1-mm TQFP outline with 0.5-mm lead pitch. The PowerPAD package has a
specially designed die mount pad that offers improved thermal capability over typical TQFP packages of the
same outline. The TI 100-TQFP PowerPAD package offers a back-side solder plane that connects directly to the
die mount pad for enhanced thermal conduction. There is no thermal requirement for soldering the back side of
the TFP401A-Q1 device to the application board, because the device power dissipation is well within the
package capability when not soldered.
Soldering the back side of the device to the PCB ground plane is recommended for electrical considerations.
Connection of the PowerPAD back side to a PCB ground plane helps to improve EMI, ground bounce, and
power-supply noise performance, because the die pad is electrically connected to the chip substrate and hence
to chip ground.
Table 4 outlines the thermal properties of the TI 100-TQFP PowerPAD package. The 100-TQFP non-PowerPAD
package is included only for reference.
