The automotive ethernet PHY chip market is experiencing growth as automotive in-vehicle electronic architectures evolve to provide higher data rates. These chips enable important connections to perform reliable communication over single, unshielded twisted pair cables across complex electronic networks in vehicles.   
 

PHY chips are engineered to endure the demanding automotive applications that components face, including expanded temperature ranges, electromagnetic interference, and persistent vibration through typical automotive duty cycles. PHY chips must also satisfy high automotive standards, including AEC-Q100 Grade 1 and IEC 61508 functional safety standards, to ascertain performance and reliability for often longer lifetime expectations of 11 or 12 years.  
 

Use of standardized IEEE Ethernet protocols is fostering consistency and interoperability across vehicles. Several protocols are currently standardizable, such as, IEEE 802.3bw (100BASE-T1) and IEEE 802.3bp (1000BASE-T1), along with proposed standard IEEE 802.3ch that provides 2.5, 5, and 10 Gbps links. These standards move integration along in passenger and commercial vehicles.  
 

The automotive industry is increasing partitioning vehicles with advanced driver-assistance systems (ADAS) and autonomous driving features; both require and utilize high-bandwidth, low-latency in-vehicle networks. PHY chips enable continuous data transmissions for radar, camera, infotainment, and sensor modules to help provide safer and more connected mobility solutions.  
 

Additional applications for PHY chips are emerging with the trend towards electrification of vehicles and vehicle to everything (V2X) communications. These semiconductors will enable next generation vehicle networking to sustain an increase in data processing while conforming to energy consumption.
 

Automotive Ethernet PHY Chip Market Trends

The market for automotive ethernet PHY chips is seeing rapid growth due to the high-bandwidth requirements of modern vehicles. High-resolution cameras for advanced driver-assistance systems (ADAS) can require data rates between 500 Mbps and 3,500 Mbps per camera, which creates a tremendous need for PHY chips to handle multiple data streams at an acceptable level of performance for in-vehicle systems.
 

Advanced driver monitoring systems, surround-view cameras, and sensors for autonomous driving are pushing PHY deployments like never before. Each sensor can generate several gigabits of data every second, requiring PHY chips that provide low-latency, high-performance transmission through complicated networks in the vehicle.
 

IEEE automotive ethernet protocol standardizations are creating a direction for the market. IEEE 802.3bw (100BASE-T1), 802.3bp (1000BASE-T1), and the new 802.3ch for 2.5G, 5G, and 10G PHYs are standardizations that provide a consistent framework for OEMs to deliver high-volume speeds of Ethernet networks across varying vehicle platforms.
 

The OPEN Alliance is continuing to define more detailed specifications for automotive PHYs, covering transmitter and receiver endpoints, as well as channel specifications. This helps to reduce the complexity of development, helps with interoperability, and provides for quicker time-to-market for Tier-1 suppliers and automotive manufacturers who use Ethernet PHYs in their vehicles from 2023-2027.
