3 说明

DP83869HM 器件是一款集成了 PMD 子层的稳健耐用型全功能千兆位物理层 (PHY) 收发器，支持 10BASE-Te、100BASE-TX 和 1000BASE-T 以太网协议。DP83869 还支持 1000BASE-X 和 100BASE-FX 光纤协议。DP83869HM 经优化可提供 ESD 保护，超过了 8kV IEC 61000-4-2 标准（直接接触）。该器件通过简化 GMII (RGMII) 和 SGMII 连接到 MAC 层。在 100M 模式中，该器件允许设计人员使用 MII 以实现低延迟。RGMII/MII 上的可编程集成终端阻抗有助于降低系统 BOM。

DP83869HM 支持非托管模式下的媒介转换。在此模式下，DP83869HM 可以运行 1000BASE-X 至 1000BASE-T 和 100BASE-FX 至 100BASE-TX 转换。

DP83869HM 还支持从 RGMII 到 SGMII 和从 SGMII 到 RGMII 的桥接转换。DP83869HM 符合 TSN 标准，可实现低延迟。
