I have questions about digital output of ADV7181D.
Can ADV7181D output 480p with 8-/10-bit ITU-R BT.656 4:2:2 YCrCb?If it can do it, are LLC 54MHz and P[19:12]/P[19:10] used for it?
Thank you!Best regards.
Could you tell me the status of this question?
Only the SDP can output on P[19:12]/P[19:10] and only the CP can process 480p. So the answer is no.. Check out Table 50 in the manual
Thank you for your reply.
So when we want ADV7181D to output 480p via "8bit" digital,do we have to use CP and DDR mode (LLC 27MHz)?
Yes the CP would output data in DDR mode and LLC would be 27MHz. Check out manual Section 9.3
Working with DDR can be difficult. Devices like the ADV7842 work in a similar DDR mode but they can also double the LLC (LLC_DLL_DOUBLE) so it effectively looks like 480p 8-bit 422 at 54MHz SDR
