Purpose

1-2

1.1 Purpose

The TFP201 EVM can be used to evaluate the TFP201 performance and de-

vice parameters, while acting as a guide for high-speed board layout. The

board allows the designer the ease of connecting directly from the output of

an existing system to the input of the flat panel display through a DVI connec-

tor. The board receives encoded serial data sent over three differential pairs

and one clock signal over a fourth differential pair that deserializes the data.

Parallel data and a clock signal are provided to an onboard transmitter, which

reserializes the data and the outputs to the connector, and then sends to the

digital connector of the display.

1.2 EVM Basic Function

The Texas Instruments TFP201 EVM kit is used to evaluate the performance

and design of the TFP201 using an existing system with a DVI interface. The

boardallowsthe designer to connect toavideo card where the dataandclock

are serialized and transmitted along four differential pairs. The receiver then

deserializesthedata,providing24bits(48bitsin2pix/clk)ofdataandaclock.

The receiver than sends the data to an onboard transmitter that reserializes

thedataandoutputsthefourdifferentialpairsthroughtheDVIconnectortothe

display. The TFP201EVM will support up to SXGA resolutions.

Overall,theboardisdesignedandoptimizedtosupporthigh-speedoperation.

In general, the board impedance should be controlled to 50 Ωandimpedance

mismatches should be kept to a minimum by designing the component pad

sizetobeascloseaspossibletothewidthoftheconnectingtransmissionline.

Inaddition, to reduce boardskew, tracelengths should be matchedasclosely

as possible.

Some features offered by this board include:

PCB and DVI cable are designed for high-speed signal integrity.

The PCB can be configured for additional power supply options.

All input/output signals are accessible.

TFP201 EVM Board Configuration and Operation

Overview

1.3 TFP201 EVM Board Configuration and Operation

TheTFP201EVMboardissimpletouse,requiringonlyafewstepstooperate:

1) Connect power supply GND and 3.3 V VCC.

2) Connect DVI input cable from PC (typically 2–3M cable).

3) Connect DVI output cable to monitor (typically 2–3M cable).

4) Power on the supply.

The TFP201 EVM board has various options for different modes of operation,

selectable by jumpers and switches. When shipped, the board is fully opera-

tional and all jumpers are in the default positions.

Note:

When handling board, ESD protection is needed.

1.3.1 Power Supply

A 3.3-V dc power supply is needed to operate the TFP201 EVM. This board

is designed for use with one or two power supplies. Two supplies can be used

ifthereisadesiretoseparatepowertotheTFP201fromtheonboardtransmit-

ter. If two supplies are used, jumper P14 must be removed; if one supply is

used, P14 must be connected. The default configuration is jumper P14 on.

1.3.2 High-Speed Data Line Probe Point

The high-speed data lines can be monitored on an oscilloscope via the SMA

connectors on the TFP201 EVM. Each data line has a 1-kΩresistor in series

with the SMA connector. This creates a 21:1 test probe point; thus the signal

is attenuated by a factor of 21. This 21:1 probe point is used to compensate

for rise time degradation through scope probes.

1.3.3 Impedance Matching

TheTMDS inputs to the TFP201 Receiver have a fixed signal-ended termina-

tion to AVDD. The TFP201 is internally optimized using a laser trim process

to precisely fix the impedance at 50 Ω. The device will function normally with

or without a resistor on the EXT_RES terminal. The fixed impedance elimi-

nates the need for an external resistor while providing optimum impedance

matching to standard 50 ΩDVI cables.

1.3.4 Transmitter Voltage Swing

The voltage swing on the transmitter can be adjusted via resistor R21. The

voltage swing can be adjusted depending on the length of the cable being

used. The larger the voltage swing, the better the signal to noise ratio.

1.3.5 Jumper Configuration

Table 1–1 and Table 1–2 reflect the default configuration of jumpers on the

TFP201 EVM board.

Note: Power supply jumpers should only be removed and replaced with power turned off.

Power supply supply jumpers can be removed to monitor individual supply currents.

Table 1–3 reflects the default configuration of Switch 1 on the TFP201 EVM

board to operate the TFP201 in normal mode. Refer to the data sheet for

specific terminal functions.
