Platform to eTSEC FIFO Restrictions
Note the following eTSEC FIFO mode maximum speed restrictions based on platform (CCB) frequency.
For FIFO GMII modes (both 8 and 16 bit) and 16-bit encoded FIFO mode:
FIFO TX/RX clock frequency <= platform clock (CCB) frequency/4.2
For example, if the platform (CCB) frequency is 533 MHz, the FIFO TX/RX clock frequency
should be no more than 127 MHz.
For 8-bit encoded FIFO mode:
FIFO TX/RX clock frequency <= platform clock (CCB) frequency/3.2
For example, if the platform (CCB) frequency is 533 MHz, the FIFO TX/RX clock frequency
should be no more than 167 MHz.

Other Input Clocks
For information on the input clocks of other functional blocks of the platform, such as SerDes and eTSEC,
see the respective sections of this document.
