The DP83869 also supports 1000BASE-X and 100BASE-FX Fiber protocols. This device interfaces to the MAC layer through Reduced GMII (RGMII) and SGMII The DP83869HM supports Media Conversion in Managed mode. In this mode, the DP83869HM can run 1000BASE-X-to-1000BASE-T and 100BASE-FX-to-100BASE-TX conversions. The DP83869HM can also support Bridge Conversion from RGMII to SGMII and SGMII to RGMII.
