NOTES
1Sample tested during initial release and after any redesign or process change that may affect this parameter.
2See Figure 1.
3The pulse widths of F1, F2, and CF are not fixed for higher output frequencies. See Frequency Outputs section.
4The CF pulse is always 35 µs in the high frequency mode. See Frequency Outputs section and Table III.
