M660-02

DUAL SAW, SELECTABLE FREQUENCY VCSO

GENERAL DESCRIPTION

PIN ASSIGNMENT (9 x 14mm SMT)

The M660-02 is a dual SAW, selectable frequency

VCSO frequency source for low-jitter clock

generation. An integrated SAW (surface

acoustic wave) delay line implements the

high-Q VCO (voltage controlled oscillator)

function, which results in low output phase

noise and very low jitter. The M660-02 is available in

a range of center frequencies from 500 to 700MHz.

Minimum pull-range is ±50 ppm (wider pull-range is

available). The M660-02 is well suited for phase-locked

loop implementations, clock and data recovery circuits,

and other timing applications in telecom and optical

fiber networking systems (e.g., OC-48, OC-192).
