Dear TI

At present, the measured data of EMC current exceeds the standard. The detailed test steps are shown in the attachment. The interference sources obtained in the experiment are 1.7M apart. The interference sources are from us: 960 RX RIN0+ RIN0------RIN3+ RIN3-,
Disconnect the 100nf capacitor of RX, and test data 30-108M are out of standard.

Please check whether the sampling frequency is caused by 1.67M in section 7.4.11.4 of our 960SPEC.Please help arrange analysis and reply at 12:00 tomorrow morning.
thank you

Hello,

What partner serializer is being used with the 960 in your setup, and what forward channel speed and mode is being used? Why did you remove the AC coupling capacitor? These capacitors are necessary for device operation.
