边界时钟有多个PTP物理通信端口和网络相连,其每个PTP端口和普通时钟的PTP端口是一样的,其中的一个端口在收到上级时钟源的PTP报文后进行终结,然后再生成新的PTP报文并向下传递。 1588v2边界时钟架构 3、透明时钟(Transparent Clock,TC) 透明时钟作为中间节点,收到PTP报文之后不进行终结,其内部有一个驻留时间桥来计算报...

It can be synchronized by any PTP/IEEE 1588 Grandmaster Clock and in turn provides time synchronization to systems either NTP- or SNTP-compatible. It comes with a built-in, highly stable and precise oscillator that is capable of bridging interferences or a temporary loss of PTP/IEEE 1588 ...
The Meinberg LANTIME time server is used around the world to provide accurate time to networks of any size. It synchronizes all PTP/IEEE 1588 compatible clients and systems either NTP- or SNTP-compatible and uses a built-in Meinberg GPS radio clock as its reference time source. A highly sta...

上电之后,时钟所做的第一件事是“听”,换句话说,它查找来自PTP通用多播地址的宣告消息。Announce消息包含发送它的时钟的属性。如果普通时钟从更好的时钟看到通告消息,则它进入从属状态,或者如果它不是从属的,则是被动的。如果普通时钟在通告超时间隔内没有看到来自更好时钟的通告消息,则它接管大师的角色。这一直持续...

Hi I am using FAMILY Cyclone V DEVICE 5CSEBA6U23I7 in my design and I an using linuxptp to tune the external PLL, in the first stemp I want to use the fpga_ptp_ref clock from FPGA side, I tried to use 0xFFD08060 regiater to change the source of the 158...
