M2020-2021 Overview
The M2020/21 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 2.5-10 GB data rates. It can serve to jitter attenuate a stratum reference clock or a recovered clock in loop timing mode.
