Ethernet bridge IC implements AVB for automotive applications

January 08, 2016 // By Graham Prophet
This automotive Ethernet AVB chipset is designed to enable reliable multimedia transmissions for next-generation infotainment and telematics.

Toshiba’s automotive-grade Ethernet bridge solution for in-vehicle infotainment (IVI) and other automotive applications, the TC9560XBG, supports standards such as IEEE 802.1AS and IEEE 802.1Qav, generally referred to as Ethernet-AVB, for stable, reliable multimedia transmissions.

The device has been developed under the ISO/TS 16949 and APQP automotive design quality system and is being AEC-Q100 qualified to guarantee quality and performance in automotive environments. The TC9560XBG is housed in a 10 x 10mm LFBGA package.

When connected to an application processor or other system-on-chip (SoC) host, the TC9560XBG allows the host device to deliver audio, video, and other data through the 10/100/1000 Ethernet network in an automotive environment. Connection to the host is via PCI Express (PCIe), HSIC or Time Division Multiplex (TDM)/I²S for audio traffic. The chipset’s RGMII/RMII/MII* interface connects to the Ethernet switch or PHY device, and both AVB and legacy traffic are supported. An on-chip ARM Cortex-M3 processor performs system control and management. TC9560AXBG also provides automotive OEMs with access to CAN-FD functionality.

*Fast Ethernet interfaces: RGMII = Reduced Gigabit Media Independent Interface; RMII = Reduced Media Independent Interface; MII = Media Independent Interface.
