Functional Diagram
General Description
The HMC874LC3C is a SiGe monolithic, ultra fast
comparator which features reduced swing PECL
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 vol-
tage swing. Overdrive and slew rate dispersion are
typically 10 ps, making the device ideal for a wide
range of applications from ATE to broadband com-
munications. The reduced swing PECL output stages
are designed to directly drive 400 mV into 50 Ohms
terminated to +1.3V while maintaining compatibility
with other PECL logic families. The HMC874LC3C
features high speed latches with programmable
hysteresis, and is configured to operate as a clocked
comparator.
