What are the characteristics required for the physical layer (PHY) of industrial Ethernet?

Since its appearance in the 1970s, Ethernet has evolved significantly and is now widely used, mainly in office networks. In Industry 4.0, which has accelerated in recent years, industrial Ethernet is the technology that supports the communication of ever-increasing amounts of information.

Industrial Ethernet requires higher robustness than standard Ethernet used in offices, etc., in order to accurately and reliably transmit and receive specific data even in harsh industrial environments such as high temperature, vibration, noise, and noise.

Industrial Ethernet PHYs ADIN1200 and ADIN1300 from Analog Devices have the following three features to achieve more accurate and reliable industrial Ethernet communication.

・Excellent delay performance that leads the industry
・Operating temperature range and EMC characteristics for industrial use
・Suitable for highly airtight environments Low power consumption

ADIN1200/ADIN1300 Operating Temperature Range, Packages, and Compliant Standards List

Low power consumption suitable for airtight environments

Many industrial applications are hermetically sealed to protect internal devices from dirt, dust, moisture, and water.

Therefore, since there is no airflow to dissipate heat from the device, it is necessary to consider power consumption in the design.

Especially in industrial applications where the ambient temperature is high, besides a wide operating temperature range, low power consumption is an important factor.

The power consumption of the ADIN1200/ADIN1300 is specified as follows, and power consumption is reduced by approximately 30% or more compared to other companies' products.

	Transmission method (RGMII)	Power consumption (typ)	I/O supply voltage
ADIN1200	100BASE-TX	175mW	3.3V
		155mW	2.5V
		139mW	1.8V
ADIN1300	1000BASE-T	425mW	3.3V
		370mW	2.5V
		332mW	1.8V
	100BASE-TX	159mW	3.3V
		148mW	2.5V
		140mW	1.8V
