8.2.1.2 Detailed Design Procedure

Signal integrity is important because as a passive switch, the device provides no signal conditioning capability.

  • Determine the loss profile between circuits that are to be muxed or demuxed.
  • Provide clean impedance and electrical length matched board traces.
  • Provide a control signal for the SEL and OEn pins.
  • Provide good ground connection to the board ground plane.
  • See the application schematics for the recommended decoupling capacitors from VCC pins to ground.
