The DP83869 is a low power, fully-featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX, and 1000BASE-T Ethernet protocols. The DP83869 also supports Fiber protocols 1000BASE-X and 100BASE-FX. Optimized for ESD protection, the DP83869 exceeds 8-kV IEC 61000-4-2 (direct contact). This device interfaces to the MAC layer through Reduced GMI I (RGMII) and SGMII. Integrated Termination Impedance on RGMII helps reduce system BOM. The DP83869EVM demonstrates all features of DP83869. The EVM supports Copper Ethernet protocols, such as 10BASE-Te, 100BASE-TX, and 1000BASE-T. The EVM also supports Fiber protocols 1000BASE-X and 100BASE-FX. The EVM has connections to use the DP83869 MAC Interface in RGMII and SGMII mode. The EVM is also optimized to demonstrate the robust EMI, EMC, and ESD performance of the DP83869 device.
