Dear Sirs,
My customer had EMI issue for their DS90UB953/954 with GPS.
They found the 954 EMI will in the GPS signal.
Here is the system block and schematics/layout as attached.
1. Once the sensor or COAX close to GPS, it will influence the GPS signal and difficult to locate.
2. After checked, the EMI frequency is around 1.575GHz.
Please help to recommend how to fix it.
Thanks.
