DS99R421 Translator Board Description:
The 20-pin IDC connector J1 accepts standard 18-bit 3-channels of LVDS RGB data
(RxIN0+/-, RxIN1+/-, RxIN2+/-) and clock (RxCLK+/-).
integrated in the DS99R421 LVDS RxIN inputs so no external resistors are required.
The translator board is powered externally from the J3 (VDD) and J4 (VSS) connectors
shown below. For the serializer to be operational, the Power Down (S1-PWDNB) and
Data Enable (S1-DEN) switches on S1 must be set HIGH. The board is factory
configured. JP1 and JP2 are configured from the factory to be shorted to VSS; these
are the unused power wires in the cable harness.
The USB connector P2 (USB-A side) on the bottom side of the board provides the
interface connection to the FPD-Link II signals to the De-serializer board. Note: P1
(mini USB) on the top side is un-stuffed and not to be used with the cable provided in
the kit.
