HMC748LC3CTR

Telecom Overview

The HMC748LC3CTR is a high-speed 2:1 selector designed for data transmission rates up to 14 Gbps. It routes one of two single-ended inputs to differential outputs based on the state of the select port. The device features programmable output voltage swing ranging from 600 mV to 1200 mV via an external VR pin, allowing for loss compensation or signal level optimization. It operates from a single +3.3 V supply with typical power consumption of 250 mW. Key electrical specifications include a propagation delay of 125 ps and rise/fall times of 22 ps. The component is housed in a RoHS-compliant 16-lead ceramic SMT package measuring 3x3 mm.
