6.4.6 SJA1110 Automotive Switch
Ethernet capabilities are extended by the use of an SJA1110A automotive Ethernet
switch with 10 ports. The SJA1110A integrates:
•
Six IEEE 100BaseT1 Phys
•
One IEEE 100BaseTX PHY
•
Two MII/RMII/RGMII interfaces
•
Four SGMII interfaces
•
An Arm Cortex-M7 based host controller
SJA1110A supports Audio Video Bridging (AVB) and the latest Time-Sensitive
Networking (TSN) standards.
