Applications Information
Suppressing Noise at the Source
* Filter all I/O signals leaving the noisy environment * Locate I/O driver circuits close to the connector * Use the longest rise/fall times possible for all digital signals
Reducing Noise at the Receiver
* Filter all I/O signals entering the unit * Locate the I/O filters as close as possible to the connector
Minimizing Noise Coupling
* * * * *
Use multilayer PCBs to minimize power and ground inductance Keep clock circuits away from the I/O connector Ground planes should be used whenever possible Minimize the loop area for all high speed signals Provide for adequate power decoupling
ESD Protection
* Locate the suppression devices as close to the I/O connector as * Minimize the PCB trace length to the suppression device * Minimize the PCB trace length for the ground return for the
suppression device possible
