AD9208 - Fine delay in both Channels

I want to introduce delays in both channels of the ADC. For this I use the registers 0x0110, 0x0111 and 0x0112. On channel A, this works perfectly, but on channel B, it does not work. The order that I follow in the record configuration for channel B is as follows:

- 0x0564 -> 0x01 (Change to channel B as output).
- 0x0110 -> 0x06 (Active fine delay and super fine delay).
- 0x0112 -> 0x0F (I enter a delay. This value is irrelevant).

Am I missing any additional records for this to work on channel B? Am I doing something wrong?

Thank you so much.

Best Regards.

  • Hi Jose,

    The registers 0x0111 and 0x0112 are local registers. So are you writing to the correct channel to issue the delay? these registers need the channel index register to perform the delay option.

    Thanks
