Introduction
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. It 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 GMII (RGMII) and SGMII.
Integrated Termination Impedance on RGMII helps reduce system BOM. The DP83869EVM will
demonstrate all features of DP83869. The EVM will support Copper Ethernet protocols like 10BASE-Te,
100BASE-TX, and 1000BASE-T. It also supports Fiber protocols 1000BASE-X and 100BASE-FX. The
EVM has connections to use the DP83869 MAC Inerface in RGMII and SGMII mode. The EVM will also
be optimized to demonstrate the robust EMI. EMC, and ESD performance of the DP83869 device.
