• Manufacturer Part Number: mt90224
• Description: 8-port Ima/tc Phy Device
• Manufacturer: Zarlink Semiconductor

Figure 17 illustrates the implementation of a mixed mode using only 1 MT90224. Links that are not used for IMA
Groups are available in TC mode. Unused links are programmed to set their outputs to high impedance mode.
