13description: |
14  The THC63LVD1024 is a dual link LVDS receiver designed to convert LVDS
15  streams to parallel data outputs. The chip supports single/dual input/output
16  modes, handling up to two LVDS input streams and up to two digital CMOS/TTL
17  outputs.
18
19  Single or dual operation mode, output data mapping and DDR output modes are
20  configured through input signals and the chip does not expose any control
21  bus.

30      The device can operate in single or dual input and output modes.
31
32      When operating in single input mode, all pixels are received on port@0,
33      and port@1 shall not contain any endpoint. In dual input mode,
34      even-numbered pixels are received on port@0 and odd-numbered pixels on
35      port@1, and both port@0 and port@1 shall contain endpoints.
36
37      When operating in single output mode all pixels are output from the first
38      CMOS/TTL port and port@3 shall not contain any endpoint. In dual output
39      mode pixels are output from both CMOS/TTL ports and both port@2 and
40      port@3 shall contain endpoints.
