HMC911LC4BTR

Overview

The HMC911LC4BTR is a broadband time delay element from Analog Devices, operating from DC to 24 GHz. It features a continuous adjustable delay range of 62 ps to 75 ps, controlled linearly by differential voltage inputs with a 1.6 Hz modulation bandwidth. The device provides integrated constant-amplitude differential outputs, adjustable via the VAC pin, and includes internal temperature compensation. It operates on a single 3.3 V supply, draws 530 mA, and utilizes a 24-pin LCC package.

Feature Summary

• Provides broadband time delay functionality across a frequency range up to 24 GHz
• Features linear monotonic delay control relative to differential control voltage inputs
• Includes internal temperature compensation and bias circuits to minimize thermal drift
• Offers integrated constant-amplitude differential output voltages with adjustable swing

Applications

• Clock and data synchronization systems
• Transmitter design for serial data transmission up to 32 Gbps

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for moisture sensitivity handling requirements due to the ceramic package type. Ensure supply chain stability as availability may be restricted. Validate that the specific suffix matches the required reel packaging configuration for surface-mount assembly processes.

Selection Notes

Select this component when precise, wideband timing adjustments are required for high-speed digital interfaces. Consider the 24-pin LCC package constraints for PCB layout and thermal management. Evaluate the need for differential versus single-ended input configurations based on system noise immunity requirements. Assess power consumption against available thermal dissipation capabilities in the target application environment.
