Description

CC2

Power supply voltage input for RF2 analog. RF2 digital, MICROWIRE, F

oLD and

Oscillator circuits. Input may range from 2.7V to 5.5V. V

CC2 must equal VCC1. Bypass

capacitors should be placed as close as possible to this pin and be connected directly

to the ground plane.

DS012332-17

Note: VCC1 supplies power to the RF1 prescaler, N-counter, R-counter, and phase detector. VCC2 supplies power to the RF2 prescaler, N-counter, phase

detector, R-counter along with the OSCin buffer, MICROWIRE, and FoLD. VCC1 and VCC2 are clamped to each other by diodes and must be run at the same

voltage level.

VP1 and VP2 can be run separately as long as VP ≥ VCC.
