Notes:
1.
LXT devices are not available with a -1L speed grade. The LX4 is not available in -3N speed grade.
2.
These parameters represent the worst-case duty cycle distortion observable at the pins of the device using LVDS output buffers. For cases where
other I/O standards are used, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical rise/fall times.
3.
The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists
for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx FPGA Editor and Timing Analyzer
tools to evaluate clock skew specific to your application.
4.
The TCKSKEW is 0.43 ns for the XA6SLX100 device using a -2 speed grade and 0.22 ns for the XC6SLX100 devices using the -2 speed grade.
