For optimal jitter tolerance and faster lock time, use the CLKIN_PERIOD attribute.
Maximum output jitter is characterized within a reasonable noise environment (150 ps input period jitter, 40 SSOs and 25% CLB
switching). 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.
The CLKFX and CLKFX180 outputs always have an approximate 50% duty cycle.
Some duty-cycle and alignment specifications include 1% of the CLKFX output period or 0.01 UI. Example: The data sheet specifies
a maximum jitter of "±[1% of CLKFX period + 300]". Assume 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. According to the data sheet, the maximum jitter is ±[100 ps + 300 ps] = ±400 ps.
Use the Spartan-3A Jitter Calculator (www.xilinx.com/support/documentation/data_sheets/s3a_jitter_calc.zip) to estimate DFS output jitter.
Use the Clocking Wizard to determine jitter for a specific design.

LOCKED when the CLKFX and
CLKFX180 signals are valid. If using
both the DLL and the DFS, use the
