Overview
The DS15EA101SQ/NOPB is an adaptive cable equalizer designed by Texas Instruments to optimize data transmission over copper cables. This device supports data rates ranging from 150 Mbps to 1.5+ Gbps and automatically adapts to equalize signals over varying cable lengths, up to lengths that attenuate the signal by 35 dB at 750 MHz. It is versatile, supporting both single-ended and differential input drive, making it suitable for equalizing coaxial cables, differential twin-ax, and twisted pair cables. The DS15EA101 operates on a single 3.3V supply, consuming 210 mW at 1.5 Gbps, and is available in a space-saving 4 x 4 mm WQFN-16 package.
