Other Parts Discussed in Thread: DS10CP154A

Dear Sir

We used TI DS25CP104A in our new project.

There is a issue be found.

The LVDS signal had be amplified by DS25CP104A, even we set the gain to minimum. And the signal which had be amplified will disturb the wifi and BLE.

If the LVDS signal do not through the IC DS25CP104A, the issue had been solved.

Could you please help to give me some advises to solve this issue?

Many thanks!

Hi,

LVDS signals are generally low EMI. It could be the layout causing the sensitivity. Without additional information about the layout and application it is difficult to help.

You could also try the DS10CP154A which has slower output edge rates.

Regards,

Lee
