SJA1105
description
The SJA1105 is an IEEE 802.3-pliant 5-port automotive Ethernet switch. Each of the five ports can be individually configured to operate in MII, RMII and RGMII modes. This arrangement provides the flexibility to connect a mix of switches, microprocessors and PHY devices such as the TJA1100 Broad R-Reach PHY from NXP Semiconductors (Ref. 1 and Ref. 2) and other mercially available Fast Ethernet and Gigabit Ethernet PHYs. The high-speed interface makes it easy to cascade multiple SJA1105s for scalability. It can be used in various automotive scenarios such as gateway applications, body domain controllers or for interconnecting multiple ECUs in a daisy chain. Audio Video Bridging (AVB) support (Ref. 3) fully leverages infotainment and advanced driver assistance systems.
The SJA1105 es in two pin-patible variants. The SJA1105EL supports Ethernet and AVB. The SJA1105TEL includes additional functionality to support Time-Triggered Ethernet (TTEthernet) and Time-Sensitive Networking...
