This section discusses interface frequency options.
3.1.6.1
This table shows the expected frequency options for SYSCLK and platform frequencies.

3.1.6.2
The platform clock frequency must be considered for proper operation of high-speed interfaces as described below.
For proper PCI Express operation, the platform clock frequency must be greater than or equal to the values shown in
and
See Section 18.1.3.2, “Link Width,” in the reference manual for your chip for PCI Express interface width details. Note that
“PCI Express link width” in the above equation refers to the negotiated link width as the result of PCI Express link training,
which may or may not be the same as the link width POR selection.
For proper serial RapidIO operation, the platform clock frequency must be greater than or equal to:
See Section 19.4, “LP-Serial Signal Descriptions,” in the reference manual for your chip for Serial RapidIO interface width and
frequency details.
