Hi,

We are  using the transceiver AD9371 in one of our projects. On board AD9371 and the complete Low power RF   (TX-1&2 , RX-1&2 , ORX- 1&2 , SNR- 1,2&3) is placed and JESD Signals are assigned to AD9371 through a high speed connector from an FPGA.

Is it required that we use an split ground planes(AGND & DGND) for better performance? Or will it be okay if we use a common ground plane?.....Is it mandatory that we should follow the recommendations of AD9371(VSSA  to AGND  and VSSD to DGND)?
