Figure 1. HMC674LC3C/HMC674LP3E Functional Block Diagram
GENERAL DESCRIPTION
The HMC674LC3C/HMC674LP3E are silicon germanium
(SiGe), monolithic, ultrafast comparators that feature reduced
swing positive emitter-coupled logic (RSPECL) output drivers
and latch inputs. These comparators support 10 Gbps operation
and provide 85 ps propagation delay and an input signal
minimum pulse width of 60 ps with 0.2 ps rms of random jitter
(RJ). Overdrive and slew rate dispersion is typically 10 ps, making
the HMC674LC3C/HMC674LP3E ideal for a wide range of
applications from ATE to broadband communications. The
RSPECL output stages directly drive 400 mV into a 50 Ω resistor
terminated to V
TT
= (V
CCO
− 2.0 V), where V
TT
is the PECL
termination voltage (see Figure 16). The HMC674LC3C/
HMC674LP3E feature a high speed latch and programmable
hysteresis. These devices can operate in either latch mode or as
a tracking comparator.
