G
The M665 is a dual SAW, selectable frequency VCSO
noise and very low jitter. The M665-01 is available in
a range of center frequencies from 125 to 177 MHz.
The M665-02 provides 500 to 708 MHz. Guaranteed
minimum pull-range of ±120 ppm meets GbE
requirements. (It also fully satisfies ±50 ppm minimum
pull-range specification commonly required.) Industry-
standard Kvco (VCO Gain) provides full replacement
compatibility. The M665 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).
