Conventional PWMs start to lose effective resolution at relatively low frequencies. Many applications can function with PWM resolutions less than eight bits, but some applications require higher resolution due to the sensitivity of the human eye. In order to achieve as much PWM resolution as possible at the necessary frequencies, the NCO may be used in conjunction with the CLC to create a very high-resolution PWM output. This application note discusses how to design a PWM by implementing CLC and NCO with the right calculations.
