General Description  
Product Features  
The PT7V4035 is a low-cost, high-performance 3.3V  
VCXO, designed to replace expensive VCXO modules.  
The on-chip voltage causes clocks to vary by ±120ppm. It  
uses an inexpensive external pullable crystal at  
35MHz to produce the same output frequency.  
3.3V operating voltage  
Uses an inexpensive external crystal  
Provide clock output enable  
On-chip VCXO with pull range of 240ppm  
VCXO tuning voltage from 0 to 3.3V  
10mA output driver at CMOS levels  
Available in SOIC package
