104 / 129 page  8 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 8.1 Application Information The DP83867 is a single port 10/100/1000 Ethernet PHY, that supports connections to an Ethernet MAC through SGMII or RGMII. Connections to the Ethernet media are made through the IEEE 802.3 defined Media Dependent Interface. When using the device for Ethernet application, there can be certain requirements to be met for normal operation of the device. The following typical application and design requirements can be used for selecting appropriate component values for DP83867. 8.2 Typical Application DP83867 10/100/1000 Mbps Ethernet Physical Layer Ethernet MAC Magnetics RJ-45 Status LEDs 25 MHz Crystal or Oscillator RGMII SGMII 10BASE-Te 100BASE-TX 1000BASE-T Figure 8-1. Typical DP83867 Application 8.2.1 Design Requirements The design requirements for the DP83867 are: • VDDA2P5 = 2.5V • VDD1P0 = 1V • VDDIO = 3.3V, 2.5V, or 1.8V • Clock Input = 25MHz DP83867CS, DP83867IS, DP83867E SNLS504F – OCTOBER 2015 – REVISED JANUARY 2025 www.ti.com 104 Submit Document Feedback Copyright © 2025 Texas Instruments Incorporated Product Folder Links: DP83867CS DP83867IS DP83867E |
