Thermal
platform. See note regarding cfg_platform_freq in Section 17, “Signal Listings” since it is a reset
configuration pin that is related to platform frequency.
18.4.2
Platform to FIFO Restrictions
Please note the following FIFO maximum speed restrictions based on platform speed.
For FIFO GMII mode:
FIFO TX/RX clock frequency <= platform clock frequency / 4.2
For example, if the platform frequency is 533MHz, the FIFO TX/RX clock frequency should be no more
than 127MHz
For FIFO encoded mode:
FIFO TX/RX clock frequency <= platform clock frequency / 3.2
For example, if the platform frequency is 533MHz, the FIFO TX/RX clock frequency should be no more
than 167MHz
