8.4 Compatibility with TI's 100BT1 PHY

Following table shows pin comparison between DP83TC811 and DP83TG720. Pins highlighted in bold need attention while designing a common board for both 100BT1 and 1000BT1 PHY. 100BT1 and 1000BT1 PHY's different BOM requirements can also be taken care by a common board.

Details and recommendation for common board design can be found in DP83TC811, DP83TG720 Rollover Document application report.
