... Product Description Peregrine’s PE3238 is a high performance integer-N PLL capable of frequency synthesis up to 1.5 GHz. The superior phase noise performance of the PE3238 is ideal for applications such as LMDS / MMDS / WLL basestations and demanding terrestrial systems. The PE3238 features a 10/11 dual modulus prescaler, counters and a phase comparator as shown in Figure 1. ...

... PE3238 Product Specification Functional Description The PE3238 consists of a prescaler, counters, a phase detector and control logic. The dual modulus prescaler divides the VCO frequency by either 10 or 11, depending on the value of the modulus select. Counters “R” and “M” divide the reference and prescaler output, respectively, by integer values stored in a 20-bit register. additional counter (“ ...
