ASSIGNMENT (5 x 7.5mm SMT)
The M675 is a VCSO (Voltage Controlled SAW
Oscillator) 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
M675
M675
results in low output phase noise and very low jitter.
The M675-01 is available in a range of center
frequencies from 125 to 175 MHz. The M675-02
provides 500 to 700 MHz. Guaranteed minimum
pull-range of ±100 ppm meets GbE requirements.
(It also fully satisfies ±50 ppm minimum pull-range
specification commonly required.) Industry-standard
Kvco (VCO Gain) provides full replacement compati-
bility. The M675 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., SONET/SDH).
