About synchronous counters ???

One application for synchronous counters would be to drive a DAC (Digital to Analog Converter) to generate a ramp voltage. If a "ripple" counter were used, the output from the DAC would have lots of "glitches" on it. Having all outputs from the counter change simultaneously minimizes the possibility of glitches.

Another application could be memory decoding. Ensuring that a single address was selected would reduce the access time.

The propagation delay in ripple counters is cumulative. That makes them difficult to use cascaded in high speed applications.
