UCC5350: improve the performance against noise in long trace application

Part Number: UCC5350

Hi Expert,

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.
