The M660-02 is a dual SAW, selectable frequency

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).

◆ Two integrated SAW devices

◆ Selectable output frequency

◆ Supports multi-rate optical interface requirements

◆ VCSO center frequencies from 500 to 700 MHz

◆ Low phase jitter 0.19ps rms typical (50kHz-80MHz)

◆ Low phase noise -70dBc/Hz @ 1kHz offset

◆ Differential 3.3V LVPECL output

◆ Single 3.3V power supply

◆ Small 9 x 14mm SMT (surface mount) package

M660-02 Dual SAW, Selectable Frequency VCSO

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
