HMC875 Series

The HMC875LC3C is a SiGe monolithic, ultra fast comparator which features reduced swing CML 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 CML output stage is designed to directly drive 400 mV into 50 Ohms terminated to GND. The HMC875LC3C features high speed latches with programmable hysteresis, and is configured to operate as a clocked comparator.ApplicationsATE ApplicationsHigh Speed InstrumentationDigital Receiver SystemsPulse SpectroscopyHigh Speed Trigger CircuitsClock & Data Restoration
