description: |
The DP83869HM device is a robust, fully-featured Gigabit (PHY) transceiver
with integrated PMD sublayers that supports 10BASE-Te, 100BASE-TX and
1000BASE-T Ethernet protocols. 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.
