CLOCK OSCILLATORS “HE” series (non-PLL based ECL) Logic: ECL square wave MERCURY Since 1973 “HE” series use fundamental mode (inverted mesa) crystal to achieve stable and clean 10KH or 100KH differential ECL signals. No multiplier, no overtone and no phase lock loop technique is used. Jitter is as low as 1ps for the 155.520 MHz for SONET/SDH applications. The inherent advantage of differential ECL signal transmission provides improved noise immunity and makes the system less susceptible to ground noise.
