Low latency, low power consumption, high EMC industrial PHY ADIN1200/ADIN1300

Ethernet has evolved greatly since its introduction in the 1970s and is now widely used mainly in office networks. Industrial Ethernet is a technology that supports information communication that is increasing every day in Industry 4.0, which has been accelerating in recent years.

Industrial ethernet must be more robust than standard office ethernet to ensure that certain data can be transmitted and received accurately, even in harsh industrial environments such as high temperatures, vibration, noise, and noise.

Analog Devices's industrial Ethernet PHY ADIN1200 and ADIN1300 provide more accurate and reliable industrial Ethernet communications with the following three features.

• Industry-leading delay performance
• Operating temperature range and EMC characteristics for industrial applications
• Low power consumption suitable for airtight environments

The ADIN 1200 and ADIN 1300 provide industry-leading low latency performance.

This reduces network cycle time, improves network refresh time, and allows more devices to connect to the network, thereby increasing operational control and security requirements for industrial Ethernet. The delay performance of ADIN 1200 and ADIN 1300 is specified as follows, and the delay is reduced by approximately 20% or more compared with other manufacturers.

(2) The MAC transmit clock does not need to be synchronized with the ADIN1300 reference clock and the Tx FIFO.

ADIN1200/ADIN1300 are guaranteed to operate over a wide temperature range. It also complies with a wide range of EMI, EMC, and ESD standards, providing robust performance in harsh factory environments.

ADIN1200/ADIN1300 Operating Temperature Ranges and Packages, Compliance List

Many industrial applications are sealed to protect internal devices from dust, dirt, moisture, and water. Therefore, there is no airflow to dissipate heat from the device, so power consumption must be considered in the design.

Low power consumption is an important factor in addition to a wide operating temperature range, especially for industrial applications with high ambient temperatures.

The power consumption of ADIN1200/ADIN1300 is regulated as follows. The power consumption is reduced by approximately 30% or more compared with other products.
