PE3293
1.8 GHz / 550 MHz Dual Fractional-N Ultra-Low Spurious PLL for Frequency Synthesis

The PE3293 is a dual fractional-N phase-lock loop (PLL) IC 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 patented spur compensation circuitry designed into the device ensures superior spur performance over the full temperature and VCO tuning range.

The PE3293 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. The 32/33 RF prescaler (PLL1) operates up to 1.8 GHz and the 16/17 IF prescaler (PLL2) operates up to 550 MHz. It is offered in a 20-lead TSSOP package.
