the Hmc675Lp3E is a siGe monolithic, ultra fast

comparator which features reduced swing (rs) cmL

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 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 Hmc675Lp3E features high

speed latch and programmable hysteresis and may

be configured to operate in either latch mode, or as a

tracking comparator.
