Note:
1. See Switching Waveforms
2. All clock output should have the same loading to achieve zero delay between the input and outputs and zero output-to-output skew. Since the
CLKOUT pin is the internal feedback to the PLL, its relative loading can adjust the input-to-output delay. If input-to-output delay adjustments
are needed, the CLKOUT load may be changed to vary the delay between the REF input to the clock outputs. Output-to-output skew includes
CLK 1-4.
3. Specifications are guaranteed by design and not production tested.
4. Measured at 100MHz.
