Notes:
1. The MMCM does not filter typical spread-spectrum input clocks because they are usually far below the bandwidth filter frequencies.
2. The static offset is measured between any MMCM outputs with identical phase.
3. Values for this parameter are available in the Clocking Wizard.
See http://www.xilinx.com/products/intellectual-property/clocking_wizard.htm
.
4. Includes global clock buffer.
5. Calculated as F
VCO
/128 assuming output duty cycle is 50%.
6. When CLKOUT4_CASCADE = TRUE, MMCM_F
OUTMIN
is 0.036 MHz.
