ADN2804 Clock and Data Recovery

The ADN2804 provides the receiver functions of quantization, signal level detect, clock and data recovery, and data retiming for 622 Mbps NRZ data. The ADN2804 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 requireme.
