Transmit Analog Power Supply (3.3V ±5%)
TVDD can be shared with DVDD. However, it is recommended that TVDD be
isolated 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
μ
F capacitor.

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.

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 avail-

be bypassed to ground through at least one 0.1
μ
F capacitor.
