UMBERS
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 isola-
tion. 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.
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 inter-
nal power plane for isolation. If an internal power plane is not available, a fer-
rite bead can be used. Each power supply pin should be bypassed to ground
through an external 0.1 F capacitor.
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 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 F capacitor.
