Media Gateway 用于监控车载以太网通信，以太网端口测试，CAN/LIN/Flexray与100Base-T1路由测试等；在BMW，AUDI，BOSCH以及国内多公司大量使用； MediaGateway from Technica Engineering is a development tool for testing and analyzing on-board vehicle networks. MediaGateway from Technica Engineering is the most widely used development and testing tool for on-board vehicle networks using 100BASE-T1. It’s in-built automotive switches and 12 x 100BASE-T1 ports enable both capture of traffic between devices while maintaining the normal communication, as well as interaction with such devices via your test set-up. It supports single and double tagging of VLANs, Mirroring, Forwarding and more. MediaGateway is excellently suitable for subsystem testing stations and can also be installed in a test vehicle without complications. It is configured conveniently via a browser through the integrated web server. An additional and optional CAN-Ethernet bi-directional conversion is available, as well as FlexRay logging via Ethernet and one SFP slot. The SFP slot supports commercial-grade SFP modules (e.g. optical or RJ-45) as well as our 100BASE-T1 SFP Module in order to get a 13th Automotive Ethernet Port or our 1000BASE-T1 SFP Module – this makes the MediaGateway ready for Automotive Gigabit Ethernet! 12 Broadcom 100BASE-T1 ports (100 MBit/s full duplex on a single unshielded twisted pair) 3 Gigabit Ethernet ports 1 SFP Gigabit Ethernet port Automotive Tyco MQS connectors for 100BASE-T1 and power supply Web server for easy configuration: Master/Slave, HalfOut/FullOut, Port Forwarding, Port Mirroring, VLAN Tagging WakeUp function by CAN Bus or Wakeline Power output for attached devices: VBAT max. 1 Ampere in total 19 status LEDs Possibility to reset to default settings by pushbutton Robust steel case Power requirement: 8 to 16 V DC, power consumption: 8 Watt Size: 195 x 143 x 33 mm 802.1AS Bridge function

汽车以太网联盟OPEN的 TC1 100BASE-T1 PMA Spec.

The TJA1101B is a 100BASE-T1-compliant Ethernet PHY optimized for automotive use cases such as gateways, IP camera links, radar modules, driver assistance systems and back-bone networks. The device provides 100 Mbit/s transmit and receive capability over a single unshielded twisted-pair cable, supporting a cable length of up to at least 15 m. The TJA1101B has been designed for automotive robustness and ISO 26262, ASIL-A compliance, while minimizing power consumption and system costs.

This reference document describes the configuration, register structure and mapping of the TJA1101A Ethernet PHY.
