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.
