I want to run PSoC5LP Delsig at 12 bits / 20kHz sample rate, continuous conversion mode. What is the clock frequency required at an accuracy of 0ppm, if I use an external clock to the DelSig.

For example when the PLL output is set to 32MHz,

The internal clock for ADC becomes 640kHz by dividing the 32MHz MASTER clock by 50.

Now the actual conv. rate is 20000
