DESCRIPTION
The ABV0211 is a monolithic low jitter and low
phase noise (-134dBc/Hz @ 10kHz offset) VCXO IC
with PECL output, for 96MHz to 200MHz output
range. It provides a low phase noise reference
frequency using a low cost crystal.
FOUT = FXIN x 8
The chip delivers an output frequency of FXIN x 8.
This makes the ABV0211 ideal for a wide range of
applications, including 155.52MHz for SONET.
