TVDD can be shared with DVDD. However, it is recommended that TVDD be
F16
isolated from the analog power supply RVDD. For best results, use an internal
E17
power plane for isolation. If an internal power plane is not available, a ferrite
bead can be used. Each power supply pin should be bypassed to ground
R4
through an external 0.1µF capacitor.

**** Receive Analog Power Supply (3.3V ±5%)
E5
RVDD should not be shared with other power supplies. It is recommended that
G16
RVDD be isolated from the digital power supply DVDD and the analog power
D16
supply TVDD. For best results, use an internal power plane for isolation. If an
V2
internal power plane is not available, a ferrite bead can be used. Each power
supply pin should be bypassed to ground through an external 0.1µF capacitor.

AVDD should be isolated from the digital power supplies. For best results, use
J2
an internal power plane for isolation. If an internal power plane is not available,
a ferrite bead can be used. Each power supply pin should be bypassed to
ground through at least one 0.1µF capacitor.
