Hello Cypress Community
I am trying to use the PRS component in PSoC Creator. One of the requirements that I have is to fix the frequency of the PRS betweeen 100KHz to 200KHz. Essentially the Bandwidth should be 100 kHz, with fixed lower and higher frequency. How can I do this in PSoC ?
Virtually,
Sherlock

Due to the definition of "random" it will be difficult to fullfill your requirements. The maximum frequency you can get will be the clock-frequency divided by two (when the output changes at two adjacent pulses). but there is no theoretical limit for the lowest frequency.

I love google !! The lowest frequency is going to be clock /Resolution and the highest logic frequency (not switching harmonics) is clock/2. \m/

Yes, as I said Clock divided by two, but your low frequency of 100kHz will not be easy to reach, even with a resolution of 2 bits and a clock of 400kHz.

or an input clock of 400kHz, maximum frequency from the PRS = 400kHz/2 = 200kHz.
And minimum frequency for resolution repeat cycle time 4 is 400kHz/4 = 100kHz. Correct ?

Yes, that is what I wanted to say. Since you may specify a resolution of 4, you'll get 15 different values (repeated) .

Bob, could you provide me a much more discrete answer. What should I do to contain my frequencis between two known frequencies from a PRS component.
I can buy you a beer, if you could help me with this.
