TAS5622A: EMI too high

Kevin Huang8

Part Number: TAS5622A

Hi Team,

My Monitor Speakers cannot pass the EMC test because the TAS5622A outputs 147.92MHZ is too high, please suggest the inductance value and capacitor specification.

Hi Kevin

For such high frequency, it's likely caused by the cable resonance. From our experience, we could try to add 10nF caps for each output cable, put the caps as close to the PCB port as you can.
