HMC875LC3C_10

HMC875LC3C v04.0810 20 Gbps Clocked COMPARATOR with RSCML OUTPUT STAGE 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: 130 mW RSPECL and RSECL Versions Available 16 Lead 3x3mm SMT Package: 9mm 2 1 COMPARATORS - SMT Typical Applications The HMC875LC3C is ideal for: • ATE Applications • High Speed Instrumentation • Digital Receiver Systems • Pulse Spectroscopy • High Speed Trigger Circuits • Clock & Data Restoration Functional Diagram General Description The HMC875LC3C is a SiGe monolithic, ultra fast comparator which features reduced swing CML 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 CML output stage is designed to directly drive 400 mV into 50 Ohms terminated to GND. The HMC875LC3C features high speed latches with programmable hysteresis, and is configured to operate as a clocked comparator.
