USB Electrical Characteristics
14 USB Electrical Characteristics
This section provides the AC timings for the USB interface.
14.1
USB Interface AC Timing Specifications
The USB Port uses the transmit clock on SCC1. Table 33 lists the USB interface timings.
15 FEC Electrical Characteristics
This section provides the AC electrical specifications for the fast Ethernet controller (FEC). Note that the
timing specifications for the MII signals are independent of system clock frequency (part speed
designation). Also, MII signals use TTL signal levels compatible with devices operating at either 5.0 or
3.3 V.
15.1
MII and Reduced MII Receive Signal Timing
The receiver functions correctly up to a MII_RX_CLK maximum frequency of 25 MHz + 1%. The
reduced MII (RMII) receiver functions correctly up to a RMII_REFCLK maximum frequency of
50 MHz + 1%. There is no minimum frequency requirement. In addition, the processor clock frequency
must exceed the MII_RX_CLK frequency 1%.
Table 34 provides information on the MII and RMII receive signal timing.
