DUAL SAW, SELECTABLE FREQUENCY VCSO  
GENERAL DESCRIPTION  
PIN ASSIGNMENT (9 x 14mm SMT)  
The M665 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 M665-01 is available in  
a range of center frequencies from 125 to 175 MHz.  
The M665-02 provides 500 to 700 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).
