How to set up the Demo Evaluation Kit:

The DS90UB901Q/902Q evaluation boards consist of two sections. The first part of the

board provides the point-to-point interface for transmitting parallel video data. The second

part of the board allows bi-directional control communication of an I

C bus control of using

a MCU/FPGA to programming a remote peripheral device via the Deserailizer.

The PCB routing for the Serializer input pins (DIN) accept incoming parallel video data at

1.8V/3.3V LVCMOS signals from J1 IDC connector. The FPD-Link III interface uses a

single twisted pair cable (provided). The output pins (ROUT) are accessed through a J7

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 serializer board and the other

side of the harness, the 5-pin mini USB jack to the Deserializer board.

This completes the FPD-Link III interface connection.

NOTE: The DS9UB901Q and DS9UB902Q 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

and datasheet for more details.

3) From the video source, connect a flat cable (not supplied) to the Serializer board and

connect another flat cable (not supplied) from the Deserializer board to the controller.

Note: For 50 ohm signal sources, provide 1.8V/3.3V LVCMOS input signal levels into

DIN[13:0],HS,VS and PCLK and add 50 ohm parallel termination resistors R3-R19 on

the DS9UB901Q Serializer board.

4) Connect the Serializer I

C ports to the I

C of the peripheral slave device. Connect the

Deserializer I

C ports to the I

C bus of the MCU/FPGA (I

C master).

5) Power for the Serializer and Deserializer boards must be supplied externally through

Power Jack (VDD). Grounds for both boards are connected through Power Jack (VSS)

(see section below).
