HMC675LC3C

HMC675LC3C v08.0811 10 GHz LATCHED COMPARATOR WITH RSCML OUTPUT STAGE Features Equivalent Input Bandwidth: 10 GHz propagation Delay: 100 ps overdrive & slew rate Dispersion: 10 ps minimum pulse Width: 60 ps resistor programmable Hysteresis Differential Latch control power Dissipation: 100 mW rspEcL and rsEcL Versions available 16 Lead 3 x 3 mm smt package: 9 mm 2 1 comparators - smt Typical Applications the Hmc675Lc3c 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 Hmc675Lc3c is a siGe monolithic, ultra fast comparator which features reduced swing (rs) cmL output drivers and latch inputs. the comparator supports 10 Gbps operation while providing 100 ps propagation delay and 60 ps minimum pulse width with 0.2 ps rms random jitter (rJ). 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 Hmc675Lc3c features high speed latch and programmable hysteresis and may be configured to operate in either latch mode, or as a tracking comparator.
