简  介:Product Specification PE3239 Product Description Peregrine’s PE3239 is a high performance integer-N PLL capable of frequency synthesis up to 2.2 GHz. The superior phase noise performance of the PE3239 is ideal for applications such as wireless local loop basestations, LMDS systems and other demanding terrestrial systems. The PE3239 features a 10/11 dual modulus prescaler, counters, phase detector and a charge pump as shown in Figure 1. Counter values are programmable through a three wire serial interface. Fabricated in Peregrine’s patented UTSi (Ultra Thin Silicon) CMOS technology, the PE3239 offers excellent RF performance with the economy and integration of conventional CMOS. 2.2 GHz Integer-N PLL for Low Phase Noise Applications Features 2.2 GHz operation 10/11 prescaler Internal phase detector with charge pump Serial programmable Low power 20 mA at 3 V Ultra-low phase noise Available in 20-lead TSSOP Figure 1.
