Notes:
To achieve good noise performance, VDD and VBIAS decoupling and protection of the receive path from
extraneous in-band signals are very important. It is recommended that the printed circuit board is laid out
with a ground plane in the CMX7163 area to provide a low impedance connection between the VSS pins
and the VDD and VBIAS decoupling capacitors.
