The comparator supports 10 Gbps operation while providing 85 ps propagation delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (RJ). 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 output stages are designed to directly drive 400 mV into 50 ohms terminated to Vtt = (Vcco - 2.0 V). The HMC674LP3E features high speed latch and programmable hysteresis and may be configured to operate in either latch mode, or as a tracking comparator.
