Notes:
1.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values cannot be guaranteed “best-case,” but if a “0” is listed,
there is no positive hold time.
2.
The values in this column apply to all XC4VFX -12 parts except XC4VFX12 -12. For XC4VFX12 -12 values, use the values in the adjacent 4VLX/SX
-12 column.
3.
These items are of interest for Carry Chain applications.
4.
XC4VFX -11 devices are 1181 MHz.
