[muRata] EMC Solutions: Noise Suppression Examples

Home > EMC Solutions > Noise Suppression Examples > DVD Players

Since very high-speed signals are transmitted on the bus lines between the MPEG2 and SDRAM chips, high levels of high-frequency noise are generated.

In these cases, the BLMxxBxxSB Series (Chip Ferrite Bead for high-speed signal lines) is used. Featuring a sharp impedance rise at the specified frequency, this filter is used to minimize distortion of the signal waveform.
