Quick Detail:
1.1 GHz/510 MHz Dual Fractional-N PLL IC for Frequency Synthesis
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.
The PE3282A provides fractional-N division with power-of-two
denominator values up to 32. This allows comparison frequencies up to 32 times the channel spacing, providing a lower phase-noise floor than
integer PLLs.
Applications:
• 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
