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.

1. IOL and IOH are 12mA and –12mA respectively for the LOCK output.
2. The PLL_EN input pin is not guaranteed to meet this specification.
3. Maximum test duration is 2.0ms, one output loaded at a time.
4. Specification value for IOZ is preliminary, will be finalized upon ‘MC’ status.
