Function
Positive Power Supply
For the digital core (1.8 V).
These pins can either be positive power supply input or
output, dependent on VSEL:
VSEL connected to V
require decoupling.
VSEL connected to V
V
devices.
Positive Power Supply
For the analog PLL
Positive Power Supply
For the digital pads(3.3 V)
For correct operation, all V
connected to positive power supply.
Power Ground
Common for all sub circuits (0 V)
For correct operation, all V
to ground.
Only for P/PG-LBGA-160-1 Package
Either usage as power ground or usage as connectors
RLAS2 of the analog switches
Voltage Select
Enables the internal voltage regulator for 3.3 V only
operation mode if connected to V
