HMC854LC5TR-R5

Signal Switches, Multiplexers, Decoders 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.
