Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the 'High-Speed PCB Layout Guidelines' application note (SLVA466) for optimal performance.
The DP83640TVVX/NOPB can be configured using the TI's Phy Utility software, which provides a graphical user interface to configure and monitor the PHY. The software can be downloaded from the TI website.
The maximum cable length supported by the DP83640TVVX/NOPB is 100 meters, as per the IEEE 802.3 standard. However, the actual cable length may vary depending on the specific application and cable quality.
TI provides a troubleshooting guide in the datasheet, which covers common issues and their solutions. Additionally, the Phy Utility software can be used to monitor and debug the PHY.
The DP83640TVVX/NOPB is a IEEE 802.3-compliant PHY, which means it is compatible with other IEEE 802.3-compliant PHY devices. However, compatibility with specific devices should be verified through testing and validation.
