HMC954LC4BTR

Analog Switches, Multiplexers, Demultiplexers Overview

The HMC954LC4B is a 2:1 multiplexer designed for data serialization up to 32 Gbps. It latches two differential CML inputs on the rising edge of the input clock and serializes data using both edges of the half-rate clock. The device operates from a single -3.3 V supply with typical power consumption of 145 mA (479 mW). It features an output level control pin (VR) for signal optimization. Inputs are internally terminated with 50 Ohms, while outputs are source terminated. Available in a ceramic ROHS-compliant 4x4 mm SMT package.
