HMC728LC3C

Telecom Overview

The HMC728LC3C is a high-speed 2:1 selector designed for data transmission rates up to 14 Gbps and select port operation up to 14 GHz. It routes one of two single-ended inputs to a differential output based on the select signal. The device operates from a single -3.3 V supply with typical power consumption of 250 mW. Key electrical parameters include a propagation delay of 125 ps, rise/fall times of 17/15 ps, and an output amplitude of 1100 mVp-p (differential). It features CML inputs terminated on-chip with 50 Ohms and is housed in a RoHS-compliant 3x3 mm ceramic SMT package.
