CLC014
Adaptive Cable Equalizer for High-Speed Data Recovery
General Description
National’s CLC014 adaptive cable equalizer is a low-cost
monolithic solution for equalizing data transmitted over cable
(or any media with similar dispersive loss characteristics).
The CLC014 simplifies the task of high-speed data recovery
with a one-chip solution and a minimal number of external
components. The equalizer automatically adapts to equalize
any cable length from zero meters to lengths 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).
The CLC014 provides superior jitter performance:
180ps
for 270 Mbps data that has passed through 200
meters of Belden 8281 cable. This exceptional perfor-
mance provides wide error margin in digital data links.
The equalizer operates on a single supply with a power con-
sumption of only 290 mW. The small 14-pin SOIC package
allows for high-density placement of components for multi-
channel applications such as routers. The equalizer oper-
ates over a wide range of data rates from less than 50 Mbps
to rates in excess of 650 Mbps.
The equalizer is flexible in allowing either single-ended or
differential input drive. Its high common mode rejection pro-
vides excellent immunity to interference from noise sources.
On-chip quantized feedback eliminates baseline wander.
Additional features include a carrier detect output and an
output mute pin which, when tied together, mute the output
when no signal is present. A buffered eye monitor output is
provided, for viewing the equalized signal prior to the com-
parator. Differential AEC pins allow the user to set the inter-
nal adaptive loop time constant with one external capacitor.
Also, the CLC014 is insensitive to the pathological patterns
inherent in the video industry standards.
