车载以太网桥接IC

现如今，越来越多的道路车辆配备了车载连接功能，以支持访问互联网和蜂窝网络，并在车载系统和设备之间以及与外部系统和服务之间共享信息。此外，对于高级驾驶员辅助系统（ADAS）和自动驾驶技术而言，低通信延迟至关重要。这些发展都需要更为复杂的汽车通信系统，而这些系统则需要可靠的传输标准提供支持，还需要实时数据传输能力。为了满足这些需求，以太网TSN标准应运而生。
TC956x系列是以太网桥接 IC，专为下一代车载网络系统设计，它们支持以太网AVB／TSN，可为车载应用提供高速同步网络系统。

*: New Product

TC9560/TC9562 series features

  • The TC9560/9562 series supports standards such as IEEE 802.1AS and IEEE 802.1Qav generally referred to as Ethernet-AVB, and such as IEEE 802.1Qbv, IEEE 802.1Qbu and IEEE 802.3br generally referred to as Ethernet TSN. Connected to an application processor or other SoC host, the TC9560/9562 series allows the host device to deliver audio, video, and data through the 10/100/1000 Ethernet network in an automotive environment.
  • The connection to the host is via PCIe® running at 2.5/5.0 GT/s (PCIe Gen1.0/2.0), 480 Mbps HSIC or TDM (Time Division Multiplex)/I2S for audio traffic.
  • Provides an Ethernet PHY interface selectable from SGMII, RGMII, RMII and MII.
  • The design target is to achieve a low-power mode that typically consumes 1 mW at room temperature (measured by Toshiba). The TC9560/9562 series typically takes only 100 ms to return to normal operation (measured by Toshiba) in order to meet the market need. The TC9560/9562 series is scheduled to obtain AEC-Q100 Grade 3 qualification.

TC9563 features

  • The TC9563 supports standards such as IEEE 802.1AS and IEEE 802.1Qav generally referred to as Ethernet-AVB, and such as IEEE 802.1Qbv, IEEE 802.1Qbu and IEEE 802.3br generally referred to as Ethernet TSN.
    Provides 2-port 10Gbps Ethernet PHY interface selectrable from USXGMII, XFI, SGMII, and RGMII.
  • The TC9563 has three PCIe® running at 2.5/5.0/8.0 GT/s (PCIe Gen1.0/2.0/3.0) switch ports for communications with the host SoC and connection to devices equipped with PCIe interfaces.
  • The PCIe switch part is configured with one 4-lane upstream port for connection with the host SoC and two 1-lane downstream ports for connection to devices with a PCIe interface.
