HMC858LC4B

Telecom Overview

The HMC858LC4B is a high-speed 2:1 differential selector designed for data transmission rates up to 14 Gbps and port operation up to 14 GHz. It routes one of two differential inputs to the output based on select signals, featuring an onboard programmable output voltage control pin (VR) for signal level optimization. The device operates from a single -3.3 V supply with typical power consumption of 221 mW. It supports both differential and single-ended outputs, includes 50 Ohm input termination, and exhibits fast rise/fall times of 19/20 ps.
