Does any one have good references on multi-layer pcb design optimisation to reduce micro switching noise pick-up We are operating a micro (switching speed 2 MHz) on a PCB with 72 dB of gain in the 5 to 1000 MHz range and need to keep the noise pick to less than -90 dBm we currently have achieved -75 dBm micro noise *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
