Description

VCC1

Power Supply for Internal 3.3 V LDO. The power supply voltage range is 4.75 V to 5.25 V. Supply pin should

be decoupled with 100 pF and 0.1 μF capacitors located close to the pin.

DECL1

Decoupling Node for 3.3 V LDO. Pin should be decoupled with 100 pF, 0.1 μF, and 10 μF capacitors

located close to the pin.

Charge Pump Output Pin. Connect this pin to VTUNE through the loop filter.
