ESCRIPTION
The M675S02 is a single frequency/single output
SAW-based VCSO for low-jitter clock generation. The
SAW (surface acoustic wave) delay line serves as a
high-Q resontaor and the low noise SiGe VCSO IC
provides a low noise floor and low 1/f phase noise. The
combination of the SAW delay line and the custom IC
result in very low phase noise and jitter performance.
The M675S02 is available in frequencies from 500 to
1000 MHz with a guaranteed minimum pull-range
of
±120
ppm. Industry-standard Kvco (VCO Gain)
provides full replacement compatibility for most
designs. The M675S02 is well suited for phase-locked
loop applications, clock and data recovery circuits and
other timing applications in telecom and optical fiber
networking systems.
