ADV7511KSTV and ADV7511KSTV-P: Are these parts interchangeable if you are not using HDCP?

Q 

What is the difference with the ADV7511KSTV versus the ADV7511KSTV-P part?
Would we be able to use the HDCP part with non-encrypted data. Are the parts
interchangeable if you are not using HDCP?




 

A 

ADV7511 contains internal HDCP keys. ADV7511P does not contain HDCP keys.
You can turn off encryption with a register bit making 7511 and 7511P the same.
It's register 0xAF bit 7-- 1 is encrypted and 0 is unencrypted.
