IEEE 802.3 Standard Ethernet Physical Layers
• Standard Ethernet has had limited use in automotive to date
– Mainly OBD applications
Why ? …
• 802.3 PHYs optimized for Enterprise, business, and consumer applications
– 100meter reach
– 4-pair per port Structured Cabling (Cat 5, 5e)
– EMC performance unspecified
• With sufficient effort & expertise, may meet some OEM’s
EMC requirements
– Plug/unplug to different link
partners
• Not representative of
automotive environment
– 802.3 PHYs not well
matched
