The SYN1588®Clock_S IP-core provides highly accurate clock synchronization compliant to the IEEE 1588 standard version 1.0 and 2.0 for Industrial Ethernet applications. It provides a high resolution, high accuracy hardware clock which uses a 96-bit wide adder based clock architecture allowing supporting input clock frequencies in the range of 10 – 200 MHz.
此外，SYN1588 CLOCK_S包括MII扫描仪单元，其扫描所有以太网流量，以寻找IEEE 1588同步分组。在检测到任何这样的分组后，它从本地时钟绘制96位宽的时间戳，并将其与状态和识别数据一起复制到时间戳FIFO中。
