PL602-03
Low Phase Noise CMOS XO (48MHz to 100MHz)
FE AT UR E S
 Low phase noise XO output for the 48MHz to
100MHz range (-130 dBc at 10kHz offset).
 12 to 25MHz crystal input.
 Integrated crystal load capacitor: no external
load capacitor required.
 Selectable High Drive (30mA) or Standard Drive
(10mA) output.
 3.3V operation.
 Available in 8-Pin TSSOP or SOIC.
DESCRIPTION
The PL602-03 is a low cost, high performance and
low phase noise XO, providing less than -130dBc at
10kHz offset in the 48MHz to 100MHz operating
range. The very low jitter makes this chip ideal for
applications requiring clean reference frequency
sources. Input crystal can range from 12 to 25MHz
(fundamental resonant mode).
