M680-02
DUAL SAW, SELECTABLE FREQUENCY VCSO
Prelimina r y Inf o r m ation
GENERAL DESCRIPTION
The M680-02 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 M680-02 is available in
a range of center frequencies from 500 to 700MHz.
Minimum pull-range is
±50 ppm (wider pull-range is
available). The M680-02 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).
FEATURES
◆ Two integrated SAW devices

◆ Low phase noise -70dBc/Hz @ 1kHz offset typical
◆ Differential 3.3V LVPECL output
◆ Single 3.3V power supply
◆ Small 5 x 7mm SMT (surface mount) package
