HMC675LP3E

Overview

The HMC675LP3E is a SiGe monolithic, ultra-fast comparator featuring reduced swing (RS) CML output drivers and latch inputs. It supports 10 Gbps operation with a typical propagation delay of 100 ps and an equivalent input bandwidth of 10 GHz. The device offers a minimum pulse width of 60 ps and 0.2 ps rms random jitter. Power dissipation is 100 mW, with supply currents of 9 mA for the input stage and 8 mA for the output stage. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Features resistor-programmable hysteresis and differential latch control for flexible configuration in either latch or tracking modes.
• Includes high-speed latch circuitry capable of acquiring input signals with a minimum pulse width of 60 ps.
• Designed with RS CML output stage optimized to directly drive 400 mV into 50 ohms terminated to ground.

Applications

• Automated Test Equipment (ATE)
• High Speed Instrumentation
• Digital Receiver Systems
• Pulse Spectroscopy
• Clock & Data Restoration

Procurement Notes

Verify the specific package marking and lot number against the datasheet requirements. Confirm that the ordering suffix matches the desired tape and reel or cut tape format. Ensure compatibility with the required operating voltage levels and termination resistors for the RS CML outputs before finalizing procurement.

Selection Notes

Select this component when a single-channel comparator with integrated latching functionality is required for high-speed digital applications. Consider the 100 ps propagation delay and low jitter specifications for timing-critical designs. Evaluate the need for programmable hysteresis to improve noise immunity in noisy environments compared to standard comparators.
