Receive Analog Power Supply (3.3V ±5%)
RVDD should not be shared with other power supplies. It is recommended that
RVDD be isolated from the digital power supply DVDD and the analog power supply
TVDD. For best results, use 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 an external 0.1
μ
F capacitor.

Transmit Analog Power Supply (3.3V ±5%)
TVDD can be shared with DVDD. However, it is recommended that TVDD be iso-
lated from the analog power supply RVDD. For best results, use 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 an external
0.1

Analog Power Supply (3.3V ±5%)
AVDD should be isolated from the digital power supplies. For best results, use 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 0.1
μ
F capacitor.

Digital Power Supply (3.3V ±5%)
DVDD should be isolated from the analog power supplies. For best results, use an
internal power plane for isolation. If an internal power plane is not available, a ferrite
bead can be used. Every two DVDD power supply pins should be bypassed to
ground through at least one 0.1
μ
F capacitor.
