Functional Diagram General Description
The HMC675LC3C is a SiGe monolithic, ultra fast OM comparator that features reduced swing (RS) CML C output drivers and latch inputs. The comparator supports 10 Gbps operation while providing 100 ps propagation delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (RJ). Overdrive and slew rate dispersion are typical y 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 HMC675LC3C features high speed latch and programmable hysteresis and may be configured to operate in either latch mode, or as a tracking comparator.
