The HMC874LC3C, HMC875LC3C, and HMC876LC3C are SiGe monolithic, 20 Gbps clocked comparators that feature high speed latches with programmable hysteresis and reduced swing PECL/CML/ECL output drivers respectively. The comparators achieve 25 Gbps operation with reduced output voltage swing while providing 120 ps clock to data output delay. Minimum pulse width is typically 60 ps, and random jitter is specified at only 0.2 ps rms. They offer 20 Gbps speed at 150 mW. This family of comparators is ideal for medical imaging applications where high speed, high performance, and low power are critical requirements.
