Maximum Input and Output Clock Rate
Maximum clock toggle rate is defined as the maximum frequency
achievable for a clock type signal at an I/O pin. The I/O pin can be a
regular I/O pin or a dedicated clock I/O pin.
The maximum clock toggle rate is different from the maximum data bit
rate. If the maximum clock toggle rate on a regular I/O pin is 300 MHz,
the maximum data bit rate for dual data rate (DDR) could be potentially
as high as 600 Mbps on the same I/O pin.
Table 5–44
specifies the maximum output clock toggle rates at default load.
Table 5–46
for non-default load.
To calculate the output toggle rate for a non-default load, use this
