Description
The PE3282A is a dual fractional-N phase-locked loop integrated circuit designed for frequency synthesis and fabricated on Peregrine’s patented UTSi® CMOS process. Each PLL includes a prescaler, phase detector, charge pump and on-board fractional spur compensation. The 32/33 RF prescaler (PLL1) operates up to 1.1 GHz and the 16/17 IF prescaler (PLL2) operates up to 510 MHz.

Features
• Modulo-32 fractional-N main counters
• On-board fractional spur compensation:
   no tuning required, stable over
   temperature
• Improved phase noise compared to
   integer-N architectures
• Low power—8.5 mA at 3 V
• Integrated 1.1 GHz ÷ 32/33 prescaler
• Integrated 510 MHz ÷ 16/17 prescaler

Applications
• Cellular handsets
• Cellular base stations
• Spread-spectrum radio
• Cordless phones
• Pagers
