DESCRIPTION
The PLL602-12 is a monolithic low jitter and low
phase noise (-134dBc/Hz @ 10kHz offset) XO IC
with LVDS output, for 96MHz to 200MHz 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 8.
This makes the PLL602-12 ideal for a wide range of
applications, including 155.52MHz for SONET.
