Cm has to be roughly above 1pF. Lower Cm values have charge sharing problems. Higher Cm values lead to more noise. For the high limitation of Cm, let me double-check.
The maximum Cm supported by PSoC CSX is 1000 pF,
CSD recommended parasitic capacitance range(Cp) differs by device family.
Is recommended Cm range(1pF – 1000pF) same for all PSoC4 device family?
If recommend range differs by device family, could you please let us know about recommended Cm range in each family?
In CSX, is there any limitation for parasitic capacitance range of TX and RX?
Is there a recommend parasitic capacitance range of TX and RX.
Or is it possible to judge whether or not CSX can drive correctly only by Cm value?
(Is not there any limitation for parasitic capacitance range of TX and RX?)
