Part Number: LMH1297
Hello,
We are investigating a radiated EMI issue in a system using the LMH1297 for 12G-SDI.
We observe a relatively strong emission near 11.88 GHz. Our initial investigation suggests that the LMH1297 SDI output path may be contributing to the emission, as the level decreases when the SDI_IO driver is powered down or when a slower slew-rate setting is used.
Could TI provide technical support for EMC/EMI troubleshooting related to the LMH1297?
We can provide the schematic, PCB layout, measurement results, and test conditions if needed. Please let us know what information would be useful for further investigation.
Best regards,
