DESCRIPTION
The ABV806X is a monolithic low jitter and low
phase noise VCXO, capable of 0.4ps RMS phase
jitter and PECL or LVDS outputs, covering a wide
frequency output range up to 640MHz. It allows the
control of the output frequency with an input voltage
(VCON), using a low cost crystal.
The ABV806X is designed to address the demanding
requirements of high performance applications such
as SONET, GPS, Video, etc.
