9.2.1.2 Detailed Design Procedure

The HD3SS3212-Q1 is a high-speed passive switch device that can behave as a mux or demux. Because this is a passive switch, signal integrity is important because the device provides no signal conditioning capability. The device can support 2 to 3 inches of board trace and a connector on either end.

To design in the HD3SS3212-Q1, the designer needs to understand the following.

  • Determine the loss profile between circuits that are to be muxed or demuxed.
  • Provide clean impedance and electrical length matched board traces.
  • Depending upon the application, determine the best place to put the AC coupling capacitor.
  • Provide a control signal for the SEL and OEn pins.
  • The thermal pad must be connected to ground.
  • See the application schematics on recommended decouple capacitors from VCC pins to ground
