How to set up the Evaluation Kit:
The PCB routing for the translator LVDS input pins (RxIN) have been laid out to plug
directly into FPD HSL Tx demo board (note only 6 bit mapping is used). The FPD-Link II
TxOUT/RxIN (DOUT/RIN) interface uses a standard USB 2.0 connector/cable
assembly. 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. Connect
the 4-pin USB A
side of cable harness to the DS99R421 board and
the other side the 5-pin mini USB jack
to the DS90UR124 de-
serializer board. This completes the FPD-Link II interface connection.
NOTE: The DS99R421 and DS90C124 are NOT USB compliant and should
not be plugged into a USB device nor should a USB device be plugged into
the evaluation boards.
not be plugged into a USB device nor should a USB device be plugged into
the evaluation 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. From the Video Decoder board, connect
a flat cable (not supplied) to the translator board and connect another flat cable
(not supplied) from the De-serializer board to the panel.

3) 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).
section below).
Evaluation Board Power Connection:
The translator and de-serializer boards must be powered by supplying power externally
through J3 (VDD) and J4 (VSS) on the translator board and J4 (VDD) and J5 (VSS) on
de-serializer board. Note +4V is the absolute MAXIMUM voltage (not operating voltage)
that should ever be applied to the translator (DS99R421) or de-serializer (DS90UR124)
VDD terminal.

Damage to the device(s) can result if the voltage maximum is
exceeded.
