FEATURES
DESCRIPTION
Texas Instruments' CLC014 adaptive cable equalizer

Automatic Equalization of Coaxial and Twisted
is a low-cost monolithic solution for equalizing data

that attenuate the signal by 40 dB at 200 MHz. This
corresponds to 300 meters of Belden 8281 or 120
meters of Category 5 UTP (unshielded twisted pair).
APPLICATIONS
SMPTE 259M Serial Digital Interfaces:
The CLC014 provides superior jitter performance:
180pspp for 270 Mbps data that has passed
NTSC/PAL, 4:2:2 Component and Wide
through 200 meters of Belden 8281 cable. This

on a single supply with a power consumption of only
290 mW. The small 14-pin SOIC package allows for

operates over a wide range of data rates from less
than 50 Mbps to rates in excess of 650 Mbps.
KEY SPECIFICATIONS
The equalizer is flexible in allowing either single-

Low Supply Current: 58 mA
Additional features include a carrier detect output and
an output mute pin which, when tied together, mute

monitor output is provided, for viewing the equalized
signal prior to the comparator. Differential AEC pins
allow the user to set the internal adaptive loop time
constant with one external capacitor. Also, the
CLC014 is insensitive to the pathological patterns
inherent in the video industry standards.
