General Description


National's CLC012 adaptive cable equalizer is a low-cost monolithic solution for equalizing data transmitted over cable (or any media with similar dispersive loss characteristics). The CLC012 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 CLC012 provides superior jitter performance: 180pspp for 270 Mbps data that has passed through 200 meters of Belden 8281 cable. This exceptional performance provides wide error margin in digital data links. The equalizer operates on a single supply with a power consumption 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 operates 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 provides excellent immunity to interference from noise sources. On-chip quantized feedback eliminates baseline wander.

Additional features include a Loss of Signal 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 comparator. Differential AEC pins allow the user to set the internal adaptive loop time constant with one external capacitor.

Note: The Early Failure Rates were calculated as point estimates. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
