Hello,
I am working on a 24+2ends segmented slider, and would like to Diplex it. I am concerned about the Cp of the segments in a diplexed configuration. I am also curious about increasing the segment height to 20-24mm, so the user has a better chance of hitting the slider that will be hidden under a wood overlay(85mm wide) with no outside visual indication the slider is beneath.
Device is PSOC 4000S - CY8C4024LQI-S412
My traces are 0.16mm wide and are an average of 120mm long total for each diplexed channel.
Slider segments are 8mm wide and 15mm in height using H/4 rule for the dual chevron and .5mm spacing as per datasheet.
4 layer FR4 1.2mm thick
3m 468MP for adhesive
1.2mm wood overlay oil/wax finish.
Should I be concerned about what I am attempting to do? It looks like the 4000s series is able to accommodate 200pF of sensor capacitance each channel will surely fall in that range.
