VCSO BASED CLOCK PLL  
GENERAL DESCRIPTION  
PIN ASSIGNMENT (9 x 9 mm SMT)  
The M1020/21 is a VCSO (Voltage Controlled SAW  
Oscillator) based clock jitter  
attenuator PLL designed for clock  
jitter attenuation and frequency  
translation. The device is ideal for  
generating the transmit reference  
clock for optical network systems  
supporting up to 2.5Gb data rates.  
It can serve to jitter attenuate a

stratum reference clock or a recovered clock in loop  
timing mode. The M1020/21 module includes a  
proprietary SAW (surface acoustic wave) delay line as  
part of the VCSO. This results in a high frequency,  
high-Q, low phase noise oscillator that assures low  
intrinsic output jitter.
