TI公司的DP83TC811S-Q1是低功耗汽车PHY 100BASE-T1以太网物理层收发器,和100BASE-T1 – IEEE 802.3bw兼容,和AEC-Q100汽车规范兼容,提供通过非屏蔽单根双绞缆线发送和接收数据所需的所有物理层功能,支持标准MII,RMII, RGMII和SGMII MAC接口以及IEEE 1588 SFD,可配置I/O电压3.3V,2.5V和1.8V,器件工作温度–40℃到 +125℃ ,主要用在骨干网,网关和车体控制以及信息娱乐系统.本文介绍了DP83TC811S-Q1主要特性,功能框图,简化电路图和多种应用电路,以及带以太网和CAN的汽车网关参考设计TIDA-01425主要特性和系统指标,框图,电路图和材料清单.

The DP83TC811S-Q1 device is an IEEE 802.3bwcompliantautomotive PHYTER™ Ethernet physicallayer transceiver. It provides all physical layerfunctions needed to transmit and receive data overunshielded single twisted-pair cables. The deviceprovides xMII flexibility with support for standard MII,RMII, RGMII, and SGMII MAC interfaces.

This device includes the Diagnostic Tool Kit,providing an extensive list of real-time monitoringtools, debug tools and test modes. Within the tool kitis the first integrated electrostatic discharge (ESD)monitoring tool. It is capable of counting ESD eventson both the xMII and MDI as well as providing realtimemonitoring through the use of a programmableinterrupt. Additionally, the DP83TC811S-Q1 includesa pseudo random binary sequence (PRBS)framegeneration tool, which is fully compatible with internal loopbacks, to transmit and receive data without theuse of a MAC. The DP83TC811S-Q1 is housed in a6.00-mm × 6.00-mm, 36-pin VQFN wettable flankpackage.
