DESCRIPTION
The ABV803X is a monolithic low jitter and low
phase noise VCXO, capable of 0.4ps RMS phase
jitter and CMOS, LVDS, or PECL outputs, covering a
wide frequency output range up to 320MHz. It allows
the control of the output frequency with an input
voltage (VCON), using a low cost crystal.
The frequency selector pads of ABV803X enable
output frequencies of (2, 4, 8, or 16) * F
XIN
. The
ABV803X is designed to address the demanding
requirements of high performance applications such
as SONET, GPS, Video, etc.
