Analog Devices Inc. ADN2819ACPZ-CML

Description
The ADN2819 is a multirate clock and data recovery IC with integrated limiting amp. It provides the receiver functions of quantization, signal level detect, and clock and data recovery at rates of OC3, OC12, OC48, Gigabit Ethernet, and 15/14 FEC rates. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. The device is intended for WDM system applications and can be used with either an external reference clock or an onchip oscillator with external crystal. Both native rates and 15/14 rate digital wrappers are supported by the ADN2819, without any change of reference clock.
