9.3 GHz Latched Comparator with RSPECL Output Stage
The HMC674LC3C 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 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 VTT = (VCCO − 2.0 V), where VTT is the PECL termination voltage (see Figure 16). The HMC674LC3C feature a high speed latch and programmable hysteresis. These devices can operate in either latch mode or as a tracking comparator.
