COMPARATORS - SMT v07.0616 Typical Applications The HMC874LC3C is ideal for: • ATE Applications • High Speed Instrumentation • Digital Receiver Systems • Pulse Spectroscopy • High Speed Trigger Circuits • Clock & Data Restoration Functional Diagram HMC874LC3C 20 Gbps CLOCKED COMPARATOR Features Propagation Delay Clock to Output: 120 ps Overdrive & Slew Rate Dispersion: 10 ps Minimum Pulse Width: 60 ps Resistor Programmable Hysteresis Differential Clock Control Input Bandwidth: 10 GHz Power Dissipation: 150 mW RSCML Version Available 16 Lead 3x3 mm SMT Package: 9 mm2 General Description The HMC874LC3C is a SiGe monolithic, ultra fast comparator. The comparator supports 20 Gbps operation while providing 120 ps clock to data output delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (RJ). 25 Gbps operation can be achieved with reduced output voltage swing. Overdrive and slew rate dispersion are typically 10 ps, making the device ideal for a wide range of applications from ATE to broadband communications. The output stages are designed to directly drive 400 mV into 50 ohms terminated to Vtt = (Vcco 2.0 V). The HMC874LC3C features high-speed latches with programmable hysteresis, and is configured to operate as a clocked comparator.
