REV. 1.0.0
TYPE
PWR
DESCRIPTION
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 0.1µF capacitor.
PWR
GND
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 0.1µF capacitor.
Transmit Analog Ground
It’s recommended that all ground pins of this device be tied together.
GND
Receive Analog Ground
It’s recommended that all ground pins of this device be tied together.
