说明

DP83TC814-Q1 器件是一款符合 IEEE 802.3bw 标准的汽车 PHYTER™ 以太网物理层收发器,可使用非屏蔽双绞线电缆。它提供通过单一屏蔽双绞线电缆发送和接收数据所需的所有物理层功能。该器件具有 xMII 灵活性,支持标准 MII、RMII、RGMII 和 SGMII MAC 接口。PHY 还在 MDI 侧集成了低通滤波器,从而减少排放。

该器件包含诊断工具套件,从而提供广泛的实时监控工具、调试工具和测试模式。该工具套件中包含首款集成式静电放电 (ESD) 监控工具。它能够对 MDI 上的 ESD 事件进行计数,并且能够通过使用可编程中断提供实时监控。此外,DP83TC814S-Q1 还包含一个伪随机二进制序列 (PRBS) 帧生成工具,该工具与内部环回完全兼容,能够在不使用 MAC 的情况下发送和接收数据。该器件采用 6.00mm × 6.00mm、36 引脚 VQFN 可湿侧面封装。该器件与 DP83TG720 (1000BASE-T1) 引脚对引脚兼容。它还与 DP83TC811 外型兼容。这将允许 DP83TC811、DP83TC812、DP83TC814 和 DP83TG720 使用单个 PCB 布局。
