HMC874LC3CTR

Overview

The HMC874LC3CTR is a SiGe monolithic ultra-fast clocked comparator supporting 20 Gbps operation. It features a 16-lead 3x3 mm SMT package with alumina body and gold over nickel plating. Key electrical parameters include a typical propagation delay of 120 ps, minimum pulse width of 60 ps, and 0.2 ps rms random jitter at 10 Gbps. The device operates on +3.3 V (Vcci), +2.0 V (Vcco), and -3 V (Vee) supplies, dissipating approximately 150 mW. It provides differential clock control and resistor-programmable hysteresis.

Feature Summary

• Supports 20 Gbps data rates with low dispersion characteristics
• Features high-speed latches with programmable hysteresis
• Designed to directly drive 400 mV into 50 ohms terminated loads
• Includes differential clock control inputs for precise timing

Applications

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

Procurement Notes

Verify the specific suffix 'CTR' against the manufacturer's official documentation to confirm reel packaging specifications and moisture sensitivity level (MSL 3). Ensure compatibility with the required thermal dissipation path, as the exposed paddle is for thermal management only and must not be DC grounded. Confirm RoHS3 compliance status prior to integration.

Selection Notes

Select this component for applications requiring sub-nanosecond response times and minimal jitter. The device is suitable for systems needing direct driving of 50-ohm terminated lines without additional buffering. Consider the power supply requirements (+3.3V, +2.0V, -3V) when designing the power distribution network. The alumina package offers robust thermal performance for high-frequency operations.
