Programmable divider for timing frequency division by integer for pulse train generation, e.g. for infra-red remote control

摘要

The programmable divider inputs a clock signal (CLKO) and produces n-1 logic combinations (Cj) of the counting signal (DECj) from a counter (1). The outputs increase in range and decrease in frequency. From the available outputs a whole number division i is selected to produce the required divided output signal (CLKi).
