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).
