DESCRIPTION
The ABV0213 is a monolithic low jitter and low
phase noise (-134dBc/Hz @ 10kHz offset) VCXO IC
with PECL output, for 192MHz to 400MHz output
range. It provides a low phase noise reference
frequency using a low cost crystal.
The chip delivers an output frequency of F
XIN
x 16.
This makes the ABV0213 ideal for a wide range of
applications.
