Using PPS ADRV9009-ZU11EG on ADRV2CRR-FMC

If you are just trying to discipline the ref clock, a common approach would be to go 1 PPS -> AD9548 -> HMC7044. If you have a high enough speed clock out from your GPS receiver you could feed it into the HMC7044 directly.

I would recommend asking in the Clocking Forum as well about GPS disciplining for HMC7044.

Thanks Travis,

I will post the question in the Clocking Forum as well. 

From the ADRV9009-ZU11EG side, do I need to do any configuration?

If there is any documentation please let me know.

You will have to update the clock chip to use another reference: https://wiki.analog.com/resources/tools-software/linux-drivers/iio-pll/hmc7044
