Board-Level Functions
2.8
MPC8308 supports a USB 2.0 high speed host/device/OTG interface through external ULPI USB PHY.
The USB connection on MPC8308_RDB is shown in
2.9
On the MPC8308_RDB_RDB board, RGMII mode is used on both eTSEC1 and eTSEC2, which are
connected to the on-board 10/100/1000 PHY (RTL8211B) and the 5-port GBE switch (VSC7385)
respectively. The I/O voltage is set to 3.3 V RGMII for RTL8211B and 2.5V RGMII for VSC7385. The
RGMII (1000 BaseT) is a source synchronous bus. For a transmit bus connection, it is synchronous to
GTX_CLK from the eTSEC module. The receive bus connection is synchronous to RX_CLK generated
