FEATURES

• Low phase noise VCXO output for the 24MHz to

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

• CMOS output.

• 12 to 25MHz crystal input.

• Integrated variable capacitors.

• Selectable High Drive (30mA) or Standard Drive

(10mA) output.

• Wide pull range (+/- 250 ppm typ.).

• Low jitter (RMS): 3ps period (1 sigma).

• 3.3V operation.

• Available in 8-Pin SOIC.

DESCRIPTION

The PLL502-02 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 12 to 25MHz (fundamental resonant

mode).
