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 is available in a space
saving 4 x 4 mm LLP-16 package which allows for high den-
sity placement of components in multi-channel applications.
Features
■ Automatic equalization of coaxial, twin-ax, and twisted pair
cables

■ Single-ended or differential input
■ 50 Ω differential outputs
■ Single 3.3V supply operation
■ Low power operation, 210 mW (typ) at 1.5 Gbps
Applications
■ Cable extention applications
■ Security cameras
■ Remote LCDs and LED pannels
■ Data recovery equalization

Input Interfacing
The DS15EA101 accepts either differential or single-ended
input. The input must be AC coupled. Transformer coupling
is not supported.
Output Interfacing
The OUT+ and OUT- outputs are internally terminated with
50Ω.
