HMC674LP3ETR

Overview

The HMC674LP3ETR is a silicon germanium monolithic ultrafast comparator featuring RSPECL output drivers and latch inputs. It supports 10 Gbps operation with an equivalent input bandwidth of 9.3 GHz typical. The device provides an 85 ps propagation delay and handles input signal minimum pulse widths of 60 ps. It operates on VCCI (3.135 V to 3.465 V), VCCO (1.8 V to 3.465 V), and VEE (-3.15 V to -2.85 V) supplies, dissipating 140 mW typical power. The component is housed in a 16-lead lead frame chip scale package.

Feature Summary

• Features reduced swing positive emitter-coupled logic output stages that directly drive 400 mV into a 50 Ω resistor terminated to the PECL termination voltage.
• Includes a high-speed latch and resistor-programmable hysteresis for configurable noise immunity and signal holding capabilities.
• Operates in either track mode or latch mode via differential latch control inputs.

Applications

• Automatic test equipment applications
• High speed instrumentation
• Digital receiver systems
• Pulse spectroscopy
• Clock and data restoration

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required temperature range and lead finish before procurement. Cross-reference the part number with current datasheet revisions to validate all electrical parameters and pin configurations.

Selection Notes

Select this component for designs requiring ultrafast comparison speeds up to 10 Gbps. Consider the 85 ps propagation delay and low jitter characteristics for precision timing applications. Evaluate the need for latch functionality versus continuous tracking mode based on system architecture requirements.

Part Context

This device belongs to the HMC674 series of silicon germanium comparators manufactured by Analog Devices. It is designed for broadband communications and high-speed digital signal processing. The LP3E variant utilizes a plastic LFCSP package, distinguishing it from the ceramic LCC versions within the same functional family.
