Other Parts Discussed in Thread: SN6505A
Team,
Could you please provide some suggestions for further EMC optimization?
(I will provide the schematics and further design details off-line)
we are currently in EMC tests with the SN6501 and are having problems achieving the desired EMC class:
- CISPR25 CP - Class 3: Deviations at approx. 97MHz
- CISPR25 E-field Class 3: deviation at 1.1MHz
We have already carried out various investigations and we always come back to the combination of transformer and push pull driver as the cause.
So far we have mainly tried to optimize the snubber.
We are now considering what further investigations we can do and what can still be optimized. Do you have any suggestions for optimization from your side?
Thanks in advance,
A.
