I am using the AD9694 and I have problem with the A/D convertion that does not start.
The input clok is 500 MHz and the analog input signal is 10MHz 800mVpp (AC coupled).
If I set the A/D in test mode forcing a ramp generation (writing the register 0x0550 0x0f) all is working correctly.
Which could be the cause that put the A/D not converting (all 4 channels) ?
Following my startup initialization:
0x12 0x28 0x4F0x12 0x28 0x0F0x12 0x22 0x040x12 0x22 0x000x12 0x62 0x080x12 0x62 0x00
0x00 0x02 0x11
# quick configuration (Lines = 2, Converters (M) = 2, Octets x frame (F) = 2) b"01-001-001"0x05 0x70 0x49
# N', N, CS0x05 0x8F 0x0F0x05 0x90 0x2F

0x01 0x1c 0x0A
#set line rate 5GBps

# Normal Mode0x00 0x02 0x00
Someone can help me how and what I have to investigate ?
What are you seeing at the output of the AD9694 when the "the conversion does not start"?
