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_TTis 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.
