Does HDMIRX (pg236) supports SCDC registers?

Hi,

HDMI RX subsystem (pg236) mentions it is HDMI2.0 compliant.

But no mention on SCDC registers support.

 

Does HDMIRX (pg236) supports SCDC registers?

 

Thanks,

Deepti V

Hey @vdeepti,

But no mention on SCDC registers support.

I don't think SCDC support is required for HDMI2.0 compliance.

 

Does HDMIRX (pg236) supports SCDC registers?

Same as with HDMI 2.0a, the fact that the SCDC register block is not even mentioned once suggests that it isn't supported at the moment. But probably a Xilinx engineer can clarify.

 

Hope this helps,

Herbert

-------------- Yes, I do this for fun!

Re: Does HDMIRX (pg236) supports SCDC registers?

Hi Herbert,

But SCDC registers are mandatory for >3.4 Gbps speed as the TMDS bit clock ratio is 1/40 and that is to be indicated through SCDC registers. 

Reference: HDMIspec2.0a, 6.1.3.2

 

Thanks,
