General Description

The HMC876LC3C is a SiGe monolithic, ultra fast comparator which features reduced swing ECL output drivers and clock inputs. The comparator supports 20 Gbps operation while providing 120 ps clock to data output delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (RJ). 25 Gbps operation can be achieved with reduced output voltage swing. Overdrive and slew rate dispersion are typically 10 ps, making the device ideal for a wide range of applications from ATE to broadband communications. The reduced swing ECL output stage is designed to directly drive 400 mV into 50 Ohms terminated to -2V. The HMC876LC3C features high speed latches with programmable hysteresis, and is confi gured to operate as a clocked comparator.
