HMC910LC4B

Overview

The HMC910LC4B is a broadband analog time delay device operating from DC to 24 GHz. It provides a continuously adjustable delay range of 70 ps, controlled linearly by the VDC voltage with a modulation bandwidth of 10 mHz. The device supports single-ended or differential inputs and outputs, featuring internal 50-ohm termination to VCC. Key electrical parameters include a power supply voltage of 3.3V (range 3V to 3.6V), typical current consumption of 475 mA, and propagation delay of 360 ps at 20 GHz. It accommodates data rates up to 32 Gbps and operates within a temperature range of -40°C to +70°C.

Feature Summary

• Internally compensated for temperature variations to minimize delay drift
• Integrated enable pin (ENB) allows for low-power shutdown mode
• Adjustable differential output voltage swing via VAC control pin
• Supports both AC and DC coupling for RF input and output signals

Applications

• Synchronization of clock and data signals
• Transponder design
• Serial data transmission systems up to 32 Gbps
• Broadband test and measurement equipment
• RF ATE applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status and MSL rating before assembly. Ensure proper ESD handling procedures are followed due to the sensitivity of the ceramic package. Cross-reference datasheet revisions to ensure compatibility with specific system requirements.

Selection Notes

Select this component when precise, wideband analog delay adjustment is required up to 24 GHz. Consider the 70 ps total range and 10 mHz modulation bandwidth for control loop design. Evaluate thermal management needs given the 475 mA typical current draw and 2.2 W continuous power dissipation capability in the alumina package.

Part Context

The HMC910LC4B belongs to the HMC910 series of broadband time delays manufactured by Analog Devices. It utilizes a 24-lead ceramic surface mount package designed for high-frequency performance. This part is distinct from digital delay lines, offering true analog phase shifting capabilities suitable for ultra-wideband signal processing.

Replacement Considerations

HMC911LC4B offers similar functionality but with different delay characteristics and packaging options.
