Synchronous Programming
For applications which can not tolerate a momentary undefined division ratio, which normally occurs while changing the
data bits (A0-A4) at random, synchronous programming can be used. Data is loaded into the counter on every rising
edge of the clock which occurs while the output (OUT) is “HIGH”. The typical minimum setup and hold times are shown
in the table below as a function of frequency. For precision applications, the rising edge of the complementary output
may be used to latch the new data bits (A0-A4), so that all bits are settled before the next load cycle.
