Questions about FPDLINK

1) Does FPD link 4 devices support connecting with FPDlink3/2 devices?

2) Does the HDCP protection support content protection only or it also protect back channel and content?

3) How do FPD link support EMI issue if customer asking CISPR-25 and/or strict EMI condition.

    Peter,

    1. Regarding on new device, please use TI's internal helpme system. new device can't be talked here;

    2. HDCP is not valid for the back channel protection;

    3. EMI is on system level design issue, cable/connector and grounding are important. FPD-Link provides low swing diff. signal, and adaptive EQ is used to compensate the link loss, which is used to mitigate the EMI concerns.

    regards,

    Steven
