HMC855LC5TR

Analog Switches, Multiplexers, Demultiplexers Overview

The HMC855LC5TR is a 1:4 demultiplexer designed for data deserialization up to 28 Gbps. It samples input data using both rising and falling edges of a half-rate clock, latching data onto four differential outputs. The device operates from a single -3.3V supply with typical power consumption of 644 mW. Key electrical parameters include a maximum data rate of 28 Gbps, a half-rate clock frequency up to 14 GHz, and output rise/fall times of 22 ps. The programmable output voltage swing ranges from 450 mV to 1144 mV via the VR pin. All inputs are CML terminated on-chip with 50 Ohms.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for moisture sensitivity labeling (MSL3) prior to soldering. Ensure handling precautions are followed due to electrostatic sensitivity. Validate that the specific TR suffix corresponds to the required reel packaging format for your assembly line.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring a 1:4 demux function at speeds up to 28 Gbps. Ensure the design supports a single -3.3V negative supply rail. Verify that the host system can accommodate the 32-lead ceramic SMT package dimensions. Consider the programmable VR pin if output amplitude adjustment is necessary for impedance matching or loss compensation in the trace layout.

Analog Switches, Multiplexers, Demultiplexers Part Context

The HMC855LC5 belongs to the Hittite Microwave Corporation product line, now integrated into Analog Devices. It is specifically categorized as a high-speed serial interface component within the MUX & DEMUX family. The LC5 suffix indicates the leadless ceramic surface-mount package variant. This part is distinct from multiplexers or lower-speed logic devices in the same series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Analog Devices resources for current lifecycle status and potential obsolescence notices before finalizing designs.
