PRODUCT SPECIFICATION  
PE3340  
3.0 GHz Integer-N PLL for Low  
Phase Noise Applications  
Product Description  
Peregrine’s PE3340 is a high performance integer-N PLL  
capable of frequency synthesis up to 3.0 GHz. The  
superior phase noise performance of the PE3340 makes  
it ideal for applications such as wireless local loop  
basestations, LMDS systems and other demanding  
terrestrial systems.  
Features  
3.0 GHz operation  
÷10/11 dual modulus prescaler  
Internal phase detector  
Serial programmable  
Low power 20 mA at 3 V  
Ultra-low phase noise  
Available in 20-lead TSSOP  
The PE3340 features a 10/11 dual modulus prescaler,  
counters and a phase comparator 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 PE3340 offers excellent  
RF performance with the economy and integration of  
conventional CMOS.
