HMC875LC3CTR

Overview

The HMC875LC3CTR is a SiGe monolithic ultra-fast clocked comparator featuring reduced swing CML output drivers. It supports 20 Gbps operation with a typical clock-to-data output delay of 120 ps and a minimum pulse width of 60 ps. The device exhibits 0.2 ps rms random jitter and typically 10 ps overdrive and slew rate dispersion. It includes high-speed latches with resistor-programmable hysteresis and differential clock control inputs. The output stage is designed to drive 400 mV into 50 ohms terminated to ground, enabling direct interfacing with standard transmission lines.
