96MHz range (-137 dBc at 10kHz offset).
CMOS output.
12 to 24MHz crystal input.
Integrated crystal load capacitor: no external
load capacitor required.
Low jitter (RMS): 3-6ps period, 7-10ps accum.
3.3V operation.
Available in 8-Pin TSSOP or SOIC.

DESCRIPTIONS
The PLL602-41 is a low cost, high performance and
low phase noise XO, providing less than -137dBc at
10kHz offset in the 48MHz to 96MHz operating
range. The very low jitter (3 to 6 ps RMS period jitter
and 7 to 10 ps RMS accumulated jitter) makes this
chip ideal for applications requiring reference fre-
quency sources. Input crystal can range from 12 to
24MHz (fundamental resonant mode).
