HMC955LC4BTR

Analog Switches - Special Purpose Overview

The HMC955LC4B is a 1-to-2 demultiplexer designed for data transmission rates up to 32 Gbps. It utilizes both rising and falling edges of a half-rate clock to sample input data sequentially, latching the sequence into differential outputs on the rising edge. The device operates from a single -3.3 V supply with a typical power consumption of 660 mW. It features an invert port for data scrambling and a programmable output voltage control pin (VR) for signal-level optimization. The component supports both single-ended and differential operation within a 24-lead ceramic SMT package.
