HMC848LC5

Overview

The HMC848LC5 is a 1:4 demultiplexer designed for high-speed data deserialization up to 45 Gbps. It utilizes both rising and falling edges of the half-rate clock to achieve efficient signal processing. The device is housed in a 32-pin TFCQFN surface-mount package with an exposed pad measuring 5x5mm, ensuring thermal performance and compact integration.

Feature Summary

• Supports data deserialization speeds up to 45 Gbps
• Operates using both rising and falling edges of the half-rate clock

Applications

• High-speed serial link deserialization
• Data communication systems requiring 1:4 splitting
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix (e.g., LC5) against the manufacturer's current product status, as some variants may be obsolete or discontinued. Confirm RoHS compliance and lead-free status through official documentation before procurement. Ensure the 32-pin TFCQFN package dimensions match the target PCB footprint requirements.

Selection Notes

Select this component when a 1:4 demux function is required at speeds approaching 45 Gbps. The half-rate clock operation simplifies timing constraints in high-speed designs. Consider the 5x5mm exposed pad package for thermal management and space-constrained applications compared to larger packages.

Part Context

The HMC848LC5 belongs to the HMC series from Analog Devices, formerly Hittite Microwave Corporation. This series focuses on microwave and RF components, including logic ICs like encoders and multiplexers. The acquisition by Analog Devices expanded their portfolio in high-frequency signal processing solutions.
