General Description
The HMC876LC3C is a SiGe monolithic, ultra fast
comparator that features reduced swing ECL output
drivers and clock inputs. The comparator supports 20
Gbps operation while providing 120 ps clock to data
output delay and 60 ps minimum pulse width with 0.2
ps rms random jitter (RJ). 25 Gbps operation can be
achieved with reduced output voltage swing. 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
ECL output stage is designed to directly drive 400 mV
into 50 ohms terminated to -2 V. The HMC876LC3C
features high-speed latches with programmable
hysteresis, and is configured to operate as a clocked
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.
