The DS15EA101 is an adaptive equalizer optimized for equal- izing data transmitted over copper cables. It operates over a wide range of data rates from 150 Mbps to 1.5+ Gbps and automatically adapts to equalize any cable length from zero meters to lengths that attenuate the signal by 35 dB at 750 MHz. It allows either single-ended or differential in- put drive, which enables equalization of coaxial cables as well as differential twin-ax and twisted pair cables. It also features an LOS output and an output en- able which, when tied together, disable the output when no signal is present. The DS15EA101 is powered from a single 3.3V supply and consumes 210 mW at 1.5 Gbps. It operates over the full −40°C to +85°C industrial temperature range and is available in a space saving 4 x 4 mm LLP-16 package which allows for high density placement of components in multi-channel ap- plications.
The DS15EA101 adaptive equalizer operates from 150 Mbps up to 1.5 Gbps and supports cable lengths that attenuate the signal by up to 35 dB at 750 MHz. It can be powered from a single 3.3 V supply and consumes 210 mW at the highest data rate, working over an industrial temperature range of –40 °C to +85 °C in a compact 4 × 4 mm LLP‑16 package.
Typical applications include cable extension for security cameras, remote LCD/LED panels, and data‑recovery equalization. The device offers both single‑ended and differential inputs, 50 Ω differential outputs, LOS detection, and an output‑enable pin. Electrical specifications, pin descriptions, and reference designs are provided for easy integration into serializer/deserializer chipsets.
