ACS8520屬于集成電路（IC）的應用特定時鐘/定時。由Semtech Corporation制造生產的ACS8520應用特定時鐘/定時專用時鐘和計時 IC（集成電路）產品族中的產品主要用于執(zhí)行與時間或頻率信息生成和分配相關的各種操作，適合的設計環(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 音頻設備、藍光光盤播放器、以太網設備、PCIe、SATA、光纖通道接口、車載娛樂總線等。

Description

The ACS8520 is a highly integrated, single-chip solution for the Synchronous Equipment Timing Source (SETS) function in a SONET or SDH Network Element. The device generates SONET or SDH Equipment Clocks (SEC) and Frame Synchronization clocks. The ACS8520 is fully compliant with the required international specifications and standards.

Features

◆ Suitable for Stratum 3, 4E, 4 and SONET Minimum Clock (SMC) or SONET/SDH Equipment Clock (SEC) applications
