FEATURES
Low phase noise output for the 96MHz to
200MHz range (-134 dBc at 10kHz offset).
PECL output.
12 to 25MHz crystal input.
Integrated crystal load capacitor: no external
load capacitor required.
Output Enable selector.
3.3V operation.
Available in 16 Pin TSSOP.
DESCRIPTION
The PLL602-11 is a monolithic low jitter and low
phase noise (-134dBc/Hz @ 10kHz offset) XO IC
with PECL 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 PLL602-11 ideal for a wide range of
applications, including 155.52MHz for SONET.
