DS15EA101
0.15 to 1.5 Gbps Adaptive Cable Equalizer with LOS
Detection
General Description
The DS15EA101 is an adaptive equalizer optimized for equal-
izing data transmitted over copper cables. The DS15EA101
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.
The DS15EA101 allows either single-ended or differential in-
put drive. This enables equalization of coaxial cables as well
as differential twin-ax and twisted pair cables.
Additional features include 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.
