DESCRIPTION
Note: ^ denotes internal pull up
The ABV0214 is a monolithic low jitter and low
phase noise (-134dBc/Hz @ 10kHz offset) VCXO IC
with LVDS output, for 192MHz to 400MHz output
range. It provides a low phase noise reference
frequency using a low cost crystal.
FOUT = FXIN x 16
The chip delivers an output frequency of FXIN x 16.
This makes the ABV0214 ideal for a wide range of
applications.
