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