SNLS614A September 2018 – December 2018 DP83869HM
The DP83869HM is a fully-featured Gigabit Physical Layer transceiver with support for Fiber and Copper Ethernet standards. It can support IEEE802.3 10BASE-Te, 100BASE-TX, and 1000BASE-T Copper Ethernet protocols, along with 100BASE-FX and 1000BASE-X Fiber Ethernet protocols.
The DP83869HM is designed for easy implementation of 10-Mbps, 100-Mbps, and 1000-Mbps Ethernet LANs. In Copper mode, the PHY can interface with twisted-pair media through magnetics. In Fiber Mode, it can interface with Fiber Optic Transceivers. This device interfaces directly to the MAC layer through the Reduced GMII (RGMII) or Serial GMII (SGMII). SGMII is available only in copper Ethernet mode. MII mode is supported for 10M and 100M speeds.
The DP83869HM supports media convertor mode to interface between copper and fiber Ethernet interface. Media convertor is available for 100M and 1000M speeds.
The DP83869HM can also support bridge mode to interface between SGMII and RGMII.
The DP83869HM offers low latency. It provides IEEE 1588 Start of Frame Delimiter indication. It has option to provide recovered clock for synchronous Ethernet application.
The DP83869HM has a TDR cable diagnostic feature for fault detection on the Ethernet cable.
