UltraCMOS® 3.5 GHz Delta-Sigma modulated Fractional-N PLL for Low Phase Noise Applications
Peregrine’s PE97632 is a high performance fractional-N PLL capable of frequency synthesis up to 3.5 GHz. The device is designed for low phase noise performance and is drop in compatible with the PE9763. The PE97632 features a ÷10/11 dual modulus prescaler, counters, a delta sigma modulator and a phase comparator. Counter values are programmable through either a serial interface or directly hard-wired. It is offered in a 68-lead CQFJ package and as DIE.
