DS90UH927Q-Q1: link with DS90UB927Q

Part Number: DS90UH927Q-Q1
Other Parts Discussed in Thread: DS90UH927QEVM

Hi Sirs,

Sorry to bother you.

Because we only have  DS90UH927QEVM and  DS90UB928QEVM.

Could we use DS90UH927QEVM and  DS90UB928QEVM together? 

Have any risk  on design?

Thanks!!

    Shucheng,
    Yes, you can link UH927 with UB928 for your debug. Please check the register 0x12[6] bit, you can set UH927 to interoperate with UB928.

    Pass RGB on DE
    Setting this bit causes RGB data to be sent
    independent of DE in DS90UH927, which can be
    used to allow DS90UH927 to interoperate with
    DS90UB926, DS90UB928, and DS90UR906.
    However, setting this bit prevents HDCP operation
    and blocks packetized audio. This bit does not need
    to be set in Backward Compatibility mode.
    0: Normal operation (default)
    1: Pass RGB independent of DE


    best regards,
    Steven
