Rx SERDES De-serializer Board:
The USB connector J2 provides the interface connection for LVDS signals to the
serializer board.
The SERDES de-serializer board is powered externally from the J4 (VDD) and J5 (VSS)
connectors shown below. For the de-serializer to be operational, the Power Down
(RPWDNB) and Receiver Enable (REN) switches on S1 and S2 must be set HIGH.
Rising or falling edge reference clock is also selected by S1: HIGH (rising) or LOW
(falling).
The 50 pin IDC Connector J3 provides access to the 24 bit LVCMOS and clock outputs.
