HMC854LC5TR

Signal Switches, Multiplexers, Decoders 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.
