I am using the ADV7619 in 2x24 SDR with OP_FORMAT_SEL[7:0] = 0x54. Currently I have 1080p60 going into the device and the LLC is 148MHz. I tried to set 98 DD A0 ; LLC Half frequency, and the LLC clock disappears. I'd like the LLC clock to be at half rate.
I'd like to keep the device in this mode so I can go back and forth between 4k and 1080p without changing OP_FORMAT_SEL.
Any advice would be greatly appreciated.
