Functional Diagram
General Description
The HMC676LC3C is a SiGe monolithic, ultra fast
comparator which features reduced swing ECL 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 ECL output stage
is designed to directly drive 400 mV into 50 Ohms
terminated to -2V. The HMC676LC3C features high
speed latch and programmable hysteresis and may
be configured to operate in either latch mode, or as a
tracking comparator.
