Part Number: TFP401A-Q1
Other Parts Discussed in Thread: TFP401, TFP501

Hi,

My customer want support Chomecast 4.0, their device is HDMI receiver side to handle HDCP encryption.

Seems TFP401 have no support HDCP, only TFP501 support this function?

And I found TFP501 have no such of information on TI website. Does TI still support for this part?

Thanks!

The HDCP functionality of the TFP501 is always available. Decryption is signaled to the HDCP receiver by the CTL3 signal encoded in the DVI signal. This encoding is accomplished by the transmitter and does not require intervention by the receiver. For proper HDCP operation, the TFP501 must have appropriate keys loaded in an external EEPROM and encrypted by the device.

I am checking to see why TFP501 is not on the TI website.

Thanks

David

The customer will need to be HDCP license adopter to purchase the part. Once they have the license, please work with our local CSR to place the order.

Thanks
