FEATURES

 Low phase noise VCXO output for the 24MHz to

50MHz range (-130 dBc at 10kHz offset)

 LVCMOS output

 12 to 25MHz crystal input

 Integrated variable capacitors

 Available with High Drive (30mA) or Standard

Drive (10mA) output

 Wide pull range (± 250 ppm typical)

 Low period jitter: 3ps RMS

 3.3V operation

 Available in 8-Pin SOP.

DESCRIPTION

The PL502-02 is a low cost, high performance, low

phase noise VCXO, providing less than -130dBc at

10kHz offset in the 24MHz to 50MHz operating

range. The very low jitter (3 ps RMS period jitter)

makes this chip ideal for applications requiring volt-

age controlled frequency sources. Input crystal can

range from 12MHz to 25MHz (fundamental resonant

mode).
