Normally, the MAC mode MII should be connected to the PHY mode MII. But in some applications, we need to
connect both MAC mode MII to each other as shown. In
is PCS to MAC connection and Port5 is MAC to MAC connection.
Through the hardware setting, it is easy to set ADM6996M/MX Port5 MII to be operating in 100M Full duplex mode.
And this kind mode (100M Full) is normally the operation mode to be with CPU, the interface connection is
described in the following diagram.
(1) CKO25M is the 25M clock driven out by ADM6996M/MX to fit 100M MII operation. This clock output provides
8mA driving capability and it can directly connected to TXCLK/RXCLK.
(2) Due to Full duplex mode, so COL is tied to GND.
