Functional Diagram
General Description
The HMC674LC3C is a SiGe monolithic, ultra fast
comparator which features reduced swing PECL output
drivers and latch inputs. The comparator supports 10
Gbps operation while providing 130 ps propagation
delay and 60 ps minimum pulse width with 0.8 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 PECL output
stages are designed to directly drive 400 mV into 50
Ohms terminated to Vcco - 2V while maintaining
compatibility with other PECL logic families. The
HMC674LC3C features high speed latch and
programmable hysteresis and may be configured
to operate in either latch mode, or as a tracking
