HMC675LP3ETR

HMC675LP3E COMPARATORS - SMT v02.0312 10 GHz LATCHED COMPARATOR WITH RSCML OUTPUT STAGE Typical Applications Features The HMC675LP3E is ideal for: Equivalent Input Bandwidth: 10 GHz • ATE Applications Propagation Delay: 100 ps • High Speed Instrumentation Overdrive & Slew Rate Dispersion: 10 ps • Digital Receiver Systems Minimum Pulse Width: 60 ps • Pulse Spectroscopy Resistor Programmable Hysteresis • High Speed Trigger Circuits Differential Latch Control • Clock & Data Restoration Power Dissipation: 100 mW RSPECL and RSECL Versions Available 16 Lead 3x3 mm SMT Package: 9 mm 2 Functional Diagram General Description The HMC675LP3E is a SiGe monolithic, ultra fast comparator that 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 HMC675LP3E features high speed latch and programmable hysteresis and may be configured to operate in either latch mode, or as a tracking comparator.
