SJA1105TELY

SJA1105TELY is an IEEE 802.3-compliant 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 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. 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. SJA1105 comes in two pin-compatible variants. The SJA1105EL supports Ethernet and AVB. SJA1105TEL includes additional functionality to support time-triggered Ethernet (TTEthernet) and time-sensitive networking (TSN).
