General Description
The HMC675LC3C is a SiGe monolithic, ultra fast
comparator that 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 HMC675LC3C features high
speed latch and programmable hysteresis and may
be configured to operate in either latch mode, or as a
tracking comparator.

Note 1: Equivalent Input Bandwidth is calculated with the following formula: Bweq=0.22/√ (TRCOMP2-TRIN2) where TRIN is the 20%/80%
transition time of a quasi-Gaussian signal applied to the comparator input, and TRCOMP is the effective transition time digitized by the
comparator.
