UltraCMOS® 3.0 GHz Delta-Sigma modulated Fractional-N PLL for Low Phase Noise Applications
Peregrine’s PE9763 is a high performance fractional-N PLL capable of frequency synthesis up to 3.0 GHz. The device is designed for superior phase noise performance while providing an order of magnitude reduction in current consumption, when compared with the existing commercial space PLLs. The PE9763 features a ÷10/11 dual modulus prescaler, counters, a delta sigma modulator, a phase comparator and a charge pump. Counter values are programmable through either a serial interface or directly hard-wired. It is offered in a 68-lead CQFJ package.
