Receiver

Pin Name

I/O

No.

Description

RxIN+

I

4

Positive LVDS differentiaI data inputs.

RxIN−

I

4

Negative LVDS differential data inputs.

RxOUT

O

28

TTL level data outputs. This includes: 8 Red, 8 Green, 8 Blue, and 3 control

lines — FPLINE, FPFRAME, DRDY (also referred to as HSYNC, VSYNC, Data

Enable).

RxCLK IN+

I

1

Positive LVDS differential clock input.

RxCLK IN−

I

1
