In my customer's application, the trace between the controller output and UCC5350 input is long, to improve the performance against noise, the solutions come in my mind include:
1. RC filter before UCC5350 input;
2. Good layout to shielded the input signal line
3. Voltage translator to convert 3.3V controller signal to 5V
Besides these solutions, do you have any other suggestions? That's better if we have some reference design circuit or app note.
