ADN2805:  1.25 Gbps Clock and Data Recovery IC

製品概要

The ADN2805 provides the receiver functions of quantization and clock and data recovery for 1.25 Gbps. The ADN2805 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 specified for −40°C to +85°C ambient temperature, unless otherwise noted. The ADN2805 is available in a compact 5 mm × 5 mm 32-lead LFCSP.
