SJA1105QELY

SJA1105QELY is a safe and secure automotive gigabit Ethernet switch that extends the capabilities of the switch with improved security-related features, extended interface options, and ISO 26262 ASIL-A compliance. It is a 5-port automotive Ethernet switch supporting IEEE Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards. Each of the five ports can be individually configured to operate at 10/100/1000Mbit/s. This feature provides the flexibility to connect any Fast/Gigabit/optical PHY or MCU/MPU to any of the ports. The new frame white/blacklisting, port-reachability, and address learning restriction features, improve switch security by limiting data processing to known frames and data sources and preventing the forwarding of erroneous or malicious data. The updated MII/RMII/RGMII interfaces offer extended IO voltages such as 1V8 and 3V3 RGMII. It features an SGMII port and remains 100% pin-compatible with the SJA1105/SJA1105T switches.
