The ADN2806 provides the receiver functions for clock and data recovery, and data retiming for 622 Mbps NRZ data. The ADN2806 automatically locks to 622 Mbps data without the need for an external reference clock or programming. In the absence of input data, the output clock drifts no more than 5%. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for -40C to +85C ambient temperature, unless otherwise noted.
