Looks like you have enough bypass caps; just be sure to place them as close as possible to the supply pins on the ICs. Good to see you have separate clk & data lines to the HV5530's; you now have total flexibility to avoid timing problems.
Be sure to provide enough spacing around high-voltage signals on your PCB. Here's a handy calculator: http://www.smps.us/pcbtracespacing.html The only suggestion is to add an ESD bleeding resistor of 1Meg (approx; not critical) between your circuit GND and the actual power-line ground if you have that connection in the case. You already have a resistive path from your HV to GND which will discharge your HV cap. When I have multiple PC boards that are cabled together, I always have ESD/bleed resistors between all power supplies and GND. Usually, the largest & cheapest SMT resistor I can buy, which is 10meg, suffices for HV supplies. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
