General Description
The HMC875LC3C is a SiGe monolithic, ultra fast
comparator which features reduced swing CML 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. Over-
drive and slew rate dispersion are typically 10 ps,
making the device ideal for a wide range of applicati-
ons 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
HMC875LC3C features high speed latches with pro-
grammable hysteresis, and is configured to operate as
a clocked comparator.
