ADN2819 - Analog Devices

ADN2819 Multirate to 2.7 Gb/s Clock and Data Recovery IC with Integrated Limiting Amp

The ADN2819 provides the receiver functions of quantization, signal level detect, and clock and data recovery at rates of OC-3, OC-12, OC-48, Gigabit Ethernet, and 15/14 FEC rates. 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, un.
