ADN2804屬于集成電路（IC）的應(yīng)用特定時鐘/定時。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADN2804應(yīng)用特定時鐘/定時專用時鐘和計時 IC（集成電路）產(chǎn)品族中的產(chǎn)品主要用于執(zhí)行與時間或頻率信息生成和分配相關(guān)的各種操作，適合的設(shè)計環(huán)境較特定，例如 AMD 和 Intel 的中央處理單元 (CPU) 或圖形處理單元 (GPU)、DVD 音頻設(shè)備、藍光光盤播放器、以太網(wǎng)設(shè)備、PCIe、SATA、光纖通道接口、車載娛樂總線等。

GENERAL DESCRIPTION

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. 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.
