ACS8530T属于集成电路（IC）的应用特定时钟/定时。由升特制造生产的ACS8530T应用特定时钟/定时专用时钟和计时 IC（集成电路）产品族中的产品主要用于执行与时间或频率信息生成和分配相关的各种操作，适合的设计环境较特定，例如 AMD 和 Intel 的中央处理单元 (CPU) 或图形处理单元 (GPU)、DVD 音频设备、蓝光光盘播放器、以太网设备、PCIe、SATA、光纤通道接口、车载娱乐总线等。

描述 Description

The ACS8530 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 ACS8530 is fully compliant with the required international specifications and standards.

特性 Features

◆ Suitable for Stratum 2, 3E, 3, 4E and 4 and SONET Minimum Clock (SMC) or SONET/SDH Equipment Clock (SEC) applications (to Telcordia 1244-CORE[19] Stratum 3E, and GR-253[17], and ITU-T G.812[10] Type III and G.813[11] specifications)

◆ Accepts 14 individual input reference clocks, all with robust input clock source quality monitoring

◆ Simultaneously generates nine output clocks, plus two sync pulse outputs

◆ Absolute Holdover accuracy better than 3 x 10-10 (manual), 7.5 x 10-14 (instantaneous); Holdover stability defined by choice of external XO
