DESCRIPTION  
The ABX0212 is a monolithic low jitter and low  
phase noise (-134dBc/Hz @ 10kHz offset) XO IC  
with LVDS output, for 96MHz to 200MHz output  
range. It provides a low phase noise reference  
frequency using a low cost crystal.  
The chip delivers an output frequency of FXIN x 8.  
This makes the ABX0212 ideal for a wide range of  
applications, including 155.52MHz for SONET.
