Overview
The DS30EA101SQ/NOPB is an adaptive cable equalizer produced by Texas Instruments. This component is optimized for equalizing data transmitted over copper cables, including both coaxial and twisted pair cables. It operates over a wide range of data rates from 150 Mbps to 3.125 Gbps, making it versatile for various high-speed data transmission applications. The equalizer automatically adjusts its gain to reverse the effects of cable loss, restoring the original signal quality. It is powered by a single 2.5V supply and consumes 115 mW (typical), operating within the full industrial temperature range of -40°C to +85°C.
