Clock Divider

Clock Divider is also called as Frequency Divider. Clock divider is a circuit, it takes a input (e.g. 100 MHz) and produce a output (e.g. 50 MHz) with lower frequency. It is used to generate different clock frequencies for different parts in the digital design.

Advantages:

1. Reduce the power consumption, in terms of slower clock.

2. Facilitate the testing and debugging, in terms of slowing down the clock.

Types: 

Divided by 2 Clock Divider, Divided by 3 Clock Divider, Divided by 4 Clock Divider, and etc.
