SI52143-A01AGMR Application Field and Working Principle

The SI52143-A01AGMR is a connectivity device that integrates a standard Ethernet physical layer transceiver, a digital clock synchronization transceiver, a real-time clock, EEPROM and supply voltage management. This device is used to receive accurately synchronized time-stamped Ethernet frames over a standard 1000BASE-T connection. It offers a great solution for distributed industrial automation, smart city and Logistics applications.

The SI52143-A01AGMR is intended for robust industrial applications where excellent clock synchronization performance and immunity to environmental disturbances are of great importance. This device operates within a wide temperature range, from -40°C to +85°C, and thus is well suited for outdoor applications. Its exceptional clock synchronization performance makes it suitable for applications requiring sub-microsecond accuracy.

Working Principle

The fundamental working principle of the SI52143-A01AGMR is based on a combination of Ethernet physical layer transceiver, digital clock synchronization transceiver, real-time clock, EEPROM and power management modules. When connected to a local clock source, this device synchronizes to the source clock and embeds it into the 1000BASE-T Ethernet frames, which it then transmits over the Ethernet link.

On the receive side, the device maintains the previously synchronized clock rate and deserializes the Ethernet frames to generate accurate time-stamped data frames. All incoming Ethernet frames are internally clocked at a nominal frequency of 8 KHz so that it can detect the embedded clock rate and synchronize it to the local clock. This process eliminates time skew and helps generate accurate time-stamped data frames.

Apart from this, the device also features an autonomous power management module that enables convenient transfer of data through 10/100/1000 Mbit/s Ethernet ports. The device can check the operating temperature of the system and shut down upon reaching the maximum threshold. Additionally, the EEPROM ensures data retention in the event of power failure.

Applications

The SI52143-A01AGMR is suitable for a wide range of industrial applications such as distributed automation, smart city and logistics. It is used for the accurate synchronization of Ethernet data frames, in addition to synchronization of the local clock to a reliable external reference clock via Ethernet. This device is ideal for environments where immunity to environmental disturbances and robust temperature range are of great importance, such as outdoor smart city applications, large-scale distributed industrial automation, and transport and logistics industry.

In smart city applications, this device can be used for monitoring of different services including utilities and infrastructure, providing insight into the operational status of such services. Moreover, its synchronization features can be utilized to accurately define broadcast timing and thus facilitate efficient implementation of large-scale service distribution networks.

The SI52143-A01AGMR can also be used in distributed industrial automation. This device can synchronize the local clock accurately with a reliable external reference clock and thus enable reliable timestamping for monitoring, control and actuation across distributed nodes. As a result, a properly synchronized clock ensures the proper functioning of distributed industrial automation networks.

Lastly, in transportation and logistics, the SI52143-A01AGMR can be used to accurately sync the local clock with remote reference clocks and thus enable efficient implementation of large-scale transport and logistics networks. This device can accurately synchronize the time-stamped data frames thus ensuring efficient operation of the logistics network.
