Hello
I'm using the SN74AVC4T774 as a buffer between Analog & Digital components
Regarding GND separation - What is your recommendations (Both design & layout) ?
The power supply in PCB#1 is referenced to AGND

I'd recommend a single ground plane, and keeping analog and digital signals in separate areas on the PCB.
But this is context dependent. See, for example, resources.altium.com/p/how-to-use-a-star-point-for-analog-ground-digital-ground-connection.
