2.7 CMC Comparison

CMC for 100BASE-T1 devices and 1000BASE-T1 devices are different. When changing between 100BASE-T1 and 1000BASE-T1, CMC needs to be changed accordingly.

The following CMCs are recommended for use with the DP83TC811:

  • Pulse Electronics (AE2002)

  • Murata (DLW43MH201XK2L; DLW32MH201XK2)

  • TDK (ACT45L-201; ACT1210L-201)

The following CMCs are recommended for use with the DP83TC812 and DP83TC814:

  • Pulse Electronics (AE2002)

  • Murata (DLW43MH201XK2L; DLW32MH201XK2)

  • TDK (ACT1210L-201)

The following CMCs are recommended for use with the DP83TG720:

  • Murata (DLW32MH101XT2)

The layout should be optimized for 1000BASE-T1 PHY when creating a PCB to support both 1000Mbps and 100Mbps PHYs.
