6 / 14 page CY23FP12-002 Document #: 38-07644 Rev. *B Page 6 of 14 Table 3 is a list of output dividers that are independently selected to connect to each output pair. In the default (pre-programmed) state of the device, S1 and S2 pins will function as indicated in Table 4. The CY23FP12-002 can be programmed to other configurations. Table 3.

Outputs will be rising edge aligned only to those outputs using this same device setting. 2. When the source of an output pair is set to [111], the output pair becomes lock indicator signal. For example, if the source of an output pair (CLKA0, CLKA1) is set to [111], the CLKA0 and CLKA1, becomes lock indicator signals. In non-invert mode, CLKA0 and CLKA1 signals will be high when the PLL is in lock mode. If CLKA0 is in an invert mode, the CLKA0 will be low and the CLKA1 will be high when the PLL is in lock mode.
