2. Can the user use "1uF cap" to replace the "33Rmagnetic beads"?(I think AC coupling is not a good solution). Hi Tony, How is the customer determining where the EMC spike is coming from? What frequency is it occurring at? Also, what i...
The ferrite beads can also be coupled between other pins for the FM tuner and the device circuitry. A car lighter adapter (CLA) coupled to the device circuitry can be configured to provide a ground signal line for use as an antenna for the FM tuner IC. Further, signal lines on a ...
1. Use multi-layerPCB boardas much as possible. Compared with double-sided PCB board, the ground plane and power plane, as well as the closely arranged signal line-ground line spacing can reduce the common mode impedance and inductive coupling, so that it can be double-sided. 1/10 to 1...
