SMT Comparators Deliver 20 Gb/s Speed at less than 150 mW Power Dissipation
Hittite Microwave Corporation has launched a family of 20 Gb/s Clocked Comparators that offer a unique combination of low propagation delay for low input overdrive while minimizing propagation dispersion and power dissipation. The HMC874LC3C, HMC875LC3C and the HMC876LC3C are appropriate for digital receivers, clock and data signal restoration, pulse spectroscopy, high speed instrumentation, medical imaging & diagnostics, and industrial systems.
The HMC874LC3C, HMC875LC3C and the HMC876LC3C are SiGe monolithic, ultra fast Clocked Comparators which feature high speed latches with programmable hysteresis, and reduced swing PECL/CML/ECL output drivers respectively. The HMC874LC3C, HMC875LC3C and the HMC876LC3C achieve 25 Gb/s 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 (RJ) is specified at only 0.2 ps rms.
The devices are unique in the market today, offering 20 Gbps speed at 150 mW, which represents 50% less power than traditional comparator solutions. This family of comparators is ideal for Automatic Test Equipment (ATE) and medical imaging applications where high speed, high performance, and low power are critical requirements.
