Put the cusomer-product that is put ADV7511 and ADV7612 on the cold room 0C to 15C.
Power-on the customer-product
Set some resisters on ADV7511
After 20-30sec, the display show the black out of 2 frame (this is trouble), otherwise show like a stormy display.
At this time, customer have catched the change phase at TXC+ of ADV7511 as for input clock.
When the customer read PLL-lock-status(0x9E), then he has catched as following.
