Purpose
1.1 Purpose
The TFP201 EVM can be used to evaluate the TFP201 performance and device 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 connector. 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 outputs of the connector, and then 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 board allows the designer to connect to a video card where the data and clock are serialized and transmitted along four differential pairs. The receiver then deserializes the data, providing 24 bits (48 bits in 2 pix/clk) of data and a clock. The receiver than sends the data to an onboard transmitter that reserializes the data and outputs the four differential pairs through the DVI connector to the display. The TFP201EVM will support up to SXGA resolutions. Overall, the board is designed and optimized to support high-speed operation. In general, the board impedance should be controlled to 50 and impedance mismatches should be kept to a minimum by designing the component pad size to be as close as possible to the width of the connecting transmission line. In addition, to reduce board skew, trace lengths should be matched as closely 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
1.3 TFP201 EVM Board Configuration and Operation
The TFP201 EVM board is simple to use, requiring only a few steps to operate: 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 operational 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 if there is a desire to separate power to the TFP201 from the onboard transmitter. 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-k resistor 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
The TMDS inputs to the TFP201 Receiver have a fixed signal-ended termination to AVDD. The TFP201 is internally optimized using a laser trim process to precisely fix the impedance at 50 . The device will function normally with or without a resistor on the EXT_RES terminal. The fixed impedance eliminates the need for an external resistor while providing optimum impedance matching to standard 50 DVI 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.

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.

Switch 2 Configuration
Table 1-4 reflects the default configuration of Switch 2 on the TFP201 EVM board to operate the transmitter in normal mode. Position 1 - Sync_cont: This pin is reserved; under normal operation it should be kept in the off position. Position 2 - PD: Power down select, this pin controls the transmitter power down mode. Under normal operation this pin should be in the off position. Position 3 - PIXS: Pixel select, this pin selects 1 pix.clk input for TFT or DSTN when in the on position or 2 pix.clk input for TFT when in the off position. The default configuration for this pin should be in the on position. Position 4 - EDGE: Input signal latch edge, when in the on position signals are latched on the falling edge of IDCK. When in the off position, signals are latched on the rising edge of IDCK. The default position for this pin is in the on position.
