minimize digital noise
I have several digital signals from a microchip into a CCD chip.
The signals coming out of the microchip is very noisy. (100mv fluctuation at 0/1 level) What is the best way to reduce the noise/glitches? The noise is small compare to the logic level, but might add some noise to the CCD output.
If the best way is to use a buffer, is there any difference between a common bus buffer/driver (double cmos inverter) and schmitt trigger buffer? The signal noise is not big enough to trigger the schmitt level.
thanks
