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 F capacitor.
Receive Analog Power Supply (3.3V ±5%)
For long haul applications, RVDD should not be shared with other power sup-
plies. 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 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-
able, a ferrite bead can be used. Every two DVDD power supply pins should
be bypassed to ground through at least one 0.1 F capacitor.
OTE
: In long haul applications where the receive inputs can be severely
attenuated, it is critical to have a clean power supply design and clean
PCB layout with respect to RVDD. It is highly recommended that
RVDD be isolated from DVDD and TVDD.
