The frequency splitter composed of TTL decimal counter

In the figure is the frequency splitter composed of TTL decimal counter. In many conditions, we need to do N spitting to the pulse sequence(N is an integral). For example, the digital clock needs 60 frequency splitting, so we get the pulses of 1Hz repeated frequencies; and also, the time standard generator needs to split the crystal oscillator output frequency. If the splitting parameter N≤10, then we only need a TTL binary-decimal counter SN7490. Usually, the frequency splitter of TTL circuits is a binary counter, which make every N input pulses launch a pulse.
