Part Number: DP83848K

EMI radiation will exceed the standard, change the external crystal oscillator 100 Ohms resistance to 1K，the frequency is not changed, but the amplitude is reduced, whether it will affect the normal operation of IC?

Hello,

Thank you for your query. The US offices are closed for July 4th. As such, I will relay this information to the team and look to get feedback around the middle of the week.

Sincerely,
Gerome

The amplitude of the crystal oscillator change after change the external resistance, Will this affect IC work?

Hello,

So long as the VIH and VIL specifications of the datasheet are met, this should be okay.
