Overview

The HMC674LC3C are silicon germanium(SiGe), monolithic, ultrafast comparators that feature reducedswing positive emitter-coupled logic (RSPECL) output driversand latch inputs. These comparators support 10 Gbps operationand provide 85 ps propagation delay and an input signalminimum pulse width of 60 ps with 0.2 ps rms of random jitter(RJ). Overdrive and slew rate dispersion is typically 10 ps, makingthe HMC674LC3C ideal for a wide range ofapplications from ATE to broadband communications. TheRSPECL output stages directly drive 400 mV into a 50 Ω resistorterminated to VTT = (VCCO − 2.0 V), where VTT is the PECLtermination voltage (see Figure 16). The HMC674LC3C feature a high speed latch and programmablehysteresis. These devices can operate in either latch mode or asa tracking comparator.
