Hello, I'm designing a burst mode receiver module for a system customer. There is a Auotmatic Threshold Controller(ATC) in this module. This ATC circuit together with Power NOISE cause many many Bit Errors. The problem is that the Power is given by the system board. The noises of VCC(3.3V) and GND(0V) are both 500mVp-p! And the minimum sensitive of the ATC is only 10mV.Well, the bit errors occur. Furthermore, the total current is about 500mA.Many passive filters will lead to drop of VCC. Any suggestion? Thanks, Lianghu __________________________________________________ Do You Yahoo!? Yahoo!
