GENERAL DESCRIPTION
The ADN2814 provides the receiver functions of quantization, signal level detect, and clock and data recovery for continuous data rates from 10 Mb/s to 675 Mb/s. The ADN2814 automatically locks to all data rates without the need for an external reference clock or programming. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for −40°C to +85°C ambient temperature, unless otherwise noted.
