The DP83869HM device is a robust, fully-featured Gigabit Physical Layer (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. Optimized for ESD protection, the DP83869HM exceeds 8-kV IEC 61000-4-2 (direct contact).This device interfaces to the MAC layer through Reduced GMII (RGMII) and SGMII. In 100M mode, the device lets the designer use MII for lower Latency. Programmable integrated termination impedance on RGMII/MII helps reduce system BOM.

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. The DP83869HM is compliant to TSN standards and offers low latency.

The DP83869HM can also generate IEEE 1588 Sync Frame Detect indications to MAC. This can reduce the jitter in Time Synchronization and help the System account for asymmetric delays in Transmission and Reception of packets.

The standard Ethernet system block diagram is shown on the first page. Designers can also use the DP83869 in Media Convertor mode, in RGMII-to-SGMII Bridge applications, and in SGMII-RGMII Bridge applications.
