Notes:
1.
2.
For optimal jitter tolerance and a faster LOCK time, use the CLKIN_PERIOD attribute.
3.
Output jitter is characterized with no input jitter. Output jitter strongly depends on the environment, including the number of SSOs, the output drive
strength, CLB utilization, CLB switching activities, switching frequency, power supply, and PCB design. The actual maximum output jitter depends on
the system application.
4.
The CLKFX, CLKFXDV, and CLKFX180 outputs have a duty cycle of approximately 50%.
5.
Some duty-cycle and alignment specifications include a percentage of the CLKFX output period. For example, this data sheet specifies a maximum
CLKFX jitter of ±(1% of CLKFX period + 200 ps). Assuming that the CLKFX output frequency is 100 MHz, the equivalent CLKFX period is 10 ns, and
1% of 10 ns is 0.1 ns or 100 ps. Accordingly, the maximum jitter is ±(100 ps + 200 ps) = ±300 ps.
6.
When using CENTER_LOW_SPREAD, CENTER_HIGH_SPREAD, the valid values for CLKFX_MULTIPLY are limited to 2 through 32, and the valid
values for CLKFX_DIVIDE are limited to 1 through 4.
