We are using SAK-TC1793F-512F270EF AB in railway application there our product observed failure in radiated emission test at around 920 MHz frequency.
During investigation we found that this is frequency harmonics generated by oscillator (CB3LV-5I-20MHz) used for controller. Layout for oscillator is done as per recommendation. As a next step we added series termination resistor with 47Ohm and then we have passed result.

Is adding 47Ohm series termination will impact any operation of SAK-TC1793F-512F270EF AB ? Can we go ahead with this solution or do you recommend any other idea for our RE problem ?
