Description

1

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.

2

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.

3

CP

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