1 1. General descriptionThe SJA1105 is an IEEE 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 BroadR-Reach PHY from NXP Semiconductors (Ref. 1 and Ref. 2) and other commercially available Fast Ethernet and Gigabit Ethernet PHYs. The high-speed interface makes it easy to cascade multiple SJA1105s for scalability.
2 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 SJA1105 comes in two pin-compatible variants. The SJA1105EL supports Ethernet and AVB. The SJA1105 TEL includes additional functionality to support Time-Triggered Ethernet (TTEthernet) and Time-Sensitive Networking (TSN).2. Features and General features 5-port store and forward architecture Each port individually configurable for MII and RMII operation at 10 Mbit/s or 100 Mbit/s and RGMII operation at 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s Interface-dependent selectable I/O supply voltages.
