N/C  
The ABV2038/-39 is a family of VCXO IC’s  
specifically designed to pull high frequency  
fundamental crystals from 65MHz to 130MHz, with  
selectable PECL or LVDS outputs.. They achieve  
very low current into the crystal resulting in better  
overall stability. Their internal varicaps allow an on  
chip frequency pulling, controlled by the VCON  
input. Their very low jitter makes them ideal for the  
most demanding timing requirements.
