Each channel provides crystal-less jitter attenuation that complies with the most stringent standards. Each channel also provides internal AMI/HDB3 encoding/decoding. To support enhanced system diagnostics, channel zero can be configured for G.772 non-intrusive monitoring of any of the other 7 channels’ receive or transmit paths. The CS61880 makes use of ultra low power matched im- pedance transmitters and receivers to reduce power beyond that achieved by traditional driver designs. By achieving a more precise line match, this technique also provides superior return loss characteristics. Additional- ly, the internal line matching circuitry reduces the external component count. All transmitters have controls for independent power down and High-Z. Each receiver provides reliable data recovery with over 12 dB of cable attenuation. The receiver also incorpo- rates LOS detection compliant to the most recent specifications.
