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.
