Hi Team,
Please help us support SN65C3221. Customer is evaluating the device looking into the waveforms.At DOUT, they observed jaggy waveform. They are using the recommended cap value for each caps, C1 to C4 = 0.1uF @ VCC=3.3V.
Q). What would be the root cause for this jaggy output ?
It seems to be the switching waveform of the charge pumps. Lack of DC bias characteristics of the caps ?
We can share the schematic and the waveform information. Could you please allow us to discuss offline ? Please email me to the following email address.
