How to use AD9398 with external HDCP key

Question asked by Kikka on Apr 6, 2011

We use AD9398 with external HDCP key.

 

But HDCP authentification is not completed.

(Astro VG-849C -----> AD9398)

It seems that KSV of Rx is read correctly, but R0 of Rx = "0000" and register 0x2F = 67h(HDCP Keys Read=0).

(Refer to attached file)

 

Should we set any register for enabling external HDCP key?

And would you please tell us advice for solving this issue?
