1 Sample tested during initial release and after any redesign or process changes that might affect this parameter.

2 See Figure 2.

3 The pulse widths of F1, F2, and CF are not fixed for higher output frequencies (see the Frequency Outputs section).

4 CF is not synchronous to F1 or F2 frequency outputs.

5 The CF pulse is always 1 μs in the high frequency mode (see the Frequency Outputs section).
