HMC675LC3C

HMC675LC3C is a SiGe monolithic, ultra fast comparator that features reduced swing (RS) CML output drivers and latch inputs. This comparator supports 10Gbps operation while providing 100ps propagation delay and 60ps minimum pulse width with 0.2ps rms random jitter (RJ). Overdrive and slew rate dispersion are typically 10ps, 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 HMC675LC3C features high speed latch and programmable hysteresis and may be configured to operate in either latch mode, or as a tracking comparator. Applications include high speed instrumentation, digital receiver systems, pulse spectroscopy, high speed trigger circuits, clock & data restoration, ATE applications.
