Duty Cycle SYNC Inputs
1. These tCYCLE minimum values are valid when ‘Q’ output is fed back and connected to the FEEDBACK pin. This is the configuration shown
in Figure 5b.
2. Information in Table 1 and in Note 3 of the AC specification notes describe this specification and its limits depending on what output is fed back,
and if FREQ_SEL is high or low.
