HMC876LC3CTR

HMC876LC3C v06.0614 Features The HMC876LC3C is ideal for: Propagation Delay Clock to Output: 120 ps • ATE Applications Overdrive & Slew Rate Dispersion: 10 ps • High Speed Instrumentation Minimum Pulse Width: 60 ps • Digital Receiver Systems Resistor Programmable Hysteresis • Pulse Spectroscopy Differential Clock Control • High Speed Trigger Circuits Input Bandwidth: 10 GHz • Clock & Data Restoration Power Dissipation: 150 mW TE Typical Applications RSCML and RSPECL Versions Available 16 Lead 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description LE The HMC876LC3C is a SiGe monolithic, ultra fast comparator that features reduced swing ECL output drivers and clock inputs. 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 reduced swing ECL output stage is designed to directly drive 400 mV into 50 ohms terminated to -2 V. The HMC876LC3C features high-speed latches with programmable hysteresis, and is configured to operate as a clocked comparator.
