Overview
The HMC854LC5TR is a 4:1 multiplexer designed for 28 Gbps 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 clock output, DC coupling, and CML interfaces with 50-ohm termination. It operates from a single -3.3 V supply, consumes 510 mW typical power, and supports programmable output voltage swing from 700 to 1250 mV via the VR pin.
Feature Summary
- Supports half-rate clock input and provides a quarter-rate reference clock output for synchronization.
- Features programmable differential output voltage swing controlled by an external voltage level pin.
- Utilizes DC-coupled CML inputs and outputs with integrated 50-ohm termination.
Applications
- SONET OC 192 systems
- Broadband test and measurement equipment
- Serial data transmission up to 28 Gbps
- FPGA interfacing
Procurement Notes
Verify the component against official Analog Devices documentation to confirm specifications and package details. Ensure compatibility with system requirements regarding voltage levels and interface standards before integration.
Selection Notes
Select this component for high-speed serial data applications requiring a 4:1 multiplexing function. Consider the programmable output voltage feature for signal optimization and loss compensation in broadband environments.
Part Context
The HMC854LC5 is part of the HMC854 series of multiplexers manufactured by Analog Devices. It is housed in a 32-lead ceramic SMT package measuring 5x5 mm. The device is RoHS compliant and designed for surface mount technology.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
FAQ
How does the HMC854LC5 handle clock synchronization?
The device uses both rising and falling edges of the half-rate clock to serialize data and includes a quarter-rate clock output generated on-chip to synchronize data into the mux.
What is the purpose of the VR pin?
The VR pin allows for output level control, enabling users to increase or decrease the output voltage swing for loss compensation or signal level optimization.
