Notes:
1.
LXT devices are not available with a -1L speed grade.
2.
Values for this parameter are available in the Clocking Wizard.
3.
The PLL does not filter typical spread spectrum input clocks because they are usually far below the bandwidth filter frequencies.
4.
Includes global clock buffer.
5.
Calculated as FVCO/128 assuming output duty cycle is 50%.
6.
When using CLK_FEEDBACK = CLKOUT0 with BUFIO2 feedback, the feedback frequency will be higher than the phase frequency detector
frequency. FPFDMAX = FCLKFB / CLKFBOUT_MULT
