PE3239  
Product Specification  
Functional Description  
The PE3239 consists of a prescaler, counters, a  
phase detector, charge pump 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. An additional counter (“A”) is used in  
the modulus select logic.  
The phase-frequency detector generates up and  
down frequency control signals which direct the  
charge pump operation. The control logic includes  
a selectable chip interface. Data is written into the  
internal registers via the three wire serial bus.  
There are also various operational and test modes  
and a lock detect output.
