GENERAL AC SPECIFICATION NOTES:  
1. See test circuit and waveforms.  
2. Minimum limits are guaranteed but not tested.  
3. These specifications are guaranteed but not production tested.  
4. Under equally loaded conditions, as specified under test conditions and at a fixed temperature and voltage.  
5. tCYCLE = 1/frequency at which each output (Q, Q, Q/2 or 2Q) is expected to run.  
6. With VCC fully powered-on and an output properly connected to the FEEDBACK pin, tLOCK Max. is with C1 = 0.1µF, tLOCK Min. is with C1 = 0.01µF. (Where C1 is loop filter  
capacitor shown in Figure 2).  
7. The wiring diagrams and written explanations of Figure 3 demonstrate the input and output frequency relationships for various possible feedback configurations. The allowable  
SYNC input range to stay in the phase-locked condition is also indicated. There are two allowable SYNC frequency ranges, depending on whether FREQ_SEL is HIGH or LOW.  
Also it is possible to feed back the Q5 output, thus creating a 180° phase shift between the SYNC input and the Q outputs. The table below summarizes the allowable SYNC  
frequency range for each possible configuration.
