dp83640 MII mode

Other Parts Discussed in Thread: DP83640

Hi,

In my application, DP83640 is used for ethernet communication, as the MCU I chose strongly recommend to use MII mode (RX_DV=0): TXD3=1.

Can I add a 2.2K ohms pull-up resistor to the TXD_3 signal, Is that OK?

Thank you very much!

Mac,

MII mode is the default mode for the DP83640. No straps are necessary to enable this mode.

The TXD_3 strap option is ignored if the MII_MODE strap is low. There is no need to add a pull up resistor to TXD_3 for MII mode.
