hardware connection Low pass in PSOC5LP applications

[Anonymous]

Hello, I want to make multiple applications with my PSOC5LP board (CY8C55) and I'm wondering about the possibility to make hardware connection with the LOW PASS FILTER because the values are limited to C = 5pF - 10pF and R = 200k - 1000k , we have four possibility of breaking frequency values. It's possible to add hardware connection to have more possibility of this values ?

You could always use a mux in combination with open drain outputs to switch

   

caps to ground ahead of the internal set of R, C values. The mux would select

   

the R's, each cap would have an open drain assigned to its ground side for selecting

   

the. Or use another mux to switch gorund side of cap to ground.
