1.2.8
On the MPC8349E-mITX-GP board, GMII mode is used on TSEC1 , which is connected to the on-board
10/100/1000 PHY (VSC8201). The TSEC I/O voltage is set to 3.3 V. The GMII (1000 BaseT) is a source
synchronous bus. For a transmit bus connection, it is synchronous to GTX_CLK from the TSEC module.
The receive bus connection is synchronous to RX_CLK generated from the PHY device. When the speed
is 10/100 BaseT (MII), both transmit and receive clocks are generated by the VSC8201 PHY device. The
MPC8349E MII management interface is connected to the VSC8201 only.
between the MPC8349E TSEC1 to the VSC8201.
