How to set up the Evaluation Kit:
The PCB routing for the Tx input pins (DIN) have been laid out to accept incoming
LVCMOS signals from 50-pin IDC connector. The TxOUT/RxIN (DOUT/RIN) interface
uses a single twisted pair cable (provided). The PCB routing for the Rx output pins
(ROUT) are accessed through a 50-pin IDC connector. Please follow these steps to set
up the evaluation kit for bench testing and performance measurements:
1) A two (2) meter high speed USB 2.0 cable has been included in the kit. A two (2)
meter USB connector
/
cable assembly has been included in the kit. Connect 4-pin
USB A
side of cable harness to the serializer board and the other side
5-pin mini USB jack
to the de-serializer board. This completes the FPD-
LINKII interface connection.
NOTE: The DS99R105 and DS99R106 are NOT USB compliant and should not
be plugged into a USB device nor should a USB device be plugged into the
demo boards.
2) Jumpers and switches have been configured at the factory; they should not require
any changes for immediate operation of the chipset. See text on Configuration
settings for more details.
3) From the Video Decoder board, connect a flat cable (not supplied) to the Serializer
board and connect another flat cable (not supplied) from the De-serializer board to
the panel.
Note: For non 50 ohm signal sources, provide 3.3V LVCMOS input signal
levels into DIN[23:0] and TCLK or remove the 49.9 ohm parallel termination
resistors R1-R25 on the DS99R105 Serializer board.
4) Power for the Tx and Rx boards must be supplied externally through Power Jack
(VDD). Grounds for both boards are connected through Power Jack (VSS) (see
section below).
Power Connection:
The Serializer and De-serializer boards must be powered by supplying power externally
through J4 (VDD) and J5 (VSS) on Serializer Board and J4 (VDD) and J5 (VSS) on De-
serializer board. Note +4V is the MAXIMUM voltage that should ever be applied to the
SERDES Serializer (DS99R105) or De-serializer (DS99R106) VDD terminal. Damage
to the device(s) can result if the voltage maximum is exceeded.
