Functional Diagram
General Description
The HMC674LC3C is a SiGe monolithic, ultra fast
comparator that features reduced swing (RS) PECL
output drivers and latch inputs. The comparator
supports 10 Gbps operation while providing 85 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
PECL output stages are designed to directly drive
400 mV into 50 Ohms terminated to +1.3 V 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 comparator.
