HMC854LC5TR-R5

Overview

The HMC854LC5TR-R5 is a 28 Gbps, 4:1 multiplexer designed for high-speed data serialization. It latches four differential inputs on the rising edge of the input clock and uses both edges of the half-rate clock to serialize data. The device features a quarter-rate reference clock output for synchronization and supports DC-coupled broadband operation. All CML inputs are internally terminated with 50 ohms. The component operates from a single -3.3 V supply, consumes 510 mW typical power, and delivers programmable differential output voltage swings ranging from 700 mV to 1250 mV via an external control pin.

Feature Summary

• Supports half-rate clock input with integrated quarter-rate reference clock output for system synchronization
• Features programmable differential output voltage swing controlled by an external VR pin for signal optimization
• Provides fast rise and fall times of 16 ps for high-speed data serialization applications

Applications

• SONET OC-192 systems
• Broadband test and measurement equipment
• Serial data transmission up to 28 Gbps
• FPGA interfacing

Procurement Notes

Verify the specific suffix R5 against official documentation to confirm reel packaging specifications. Confirm RoHS compliance status through current manufacturer declarations. Ensure the ordering part number matches the exact package variant required for the design. Cross-reference the datasheet revision date to validate electrical parameters against the latest release.

Selection Notes

Select this component when designing systems requiring 4:1 data serialization at rates up to 28 Gbps. The device is suitable for applications needing programmable output levels to compensate for loss or optimize signal integrity. Consider the 32-lead ceramic SMT package dimensions and thermal requirements during PCB layout. Verify compatibility with CML logic interfaces and single-ended or differential clocking schemes.

Part Context

This component belongs to the HMC854 series of multiplexers manufactured by Analog Devices Inc. It is specifically engineered for high-performance serial data transmission tasks. The device integrates necessary termination resistors and clock generation capabilities within a compact surface-mount package, simplifying circuit design for high-speed digital interfaces.

Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers. Do not assume functional equivalence with other series components without verifying pinout and electrical parameter alignment.
