    UMTS/HSPA Module Series WCDMA UGxx Audio Design Note Design Consideration 4.1. Power Supply for PCM Codec For different PCM codec, the supply voltage is different. It’s better to supply power for PCM codec with dedicated LDO, and not to share this power with other circuits. 4.2.

  • Page 19: Tdd Noise

    UMTS/HSPA Module Series WCDMA UGxx Audio Design Note 4.3. TDD Noise It is important to avoid or reduce TDD noise in audio circuit design and layout, some suggestions are listed below: Different capacitors have their own self-resonant frequencies due to the different fabrication processes and materials.
  • Page 20 UMTS/HSPA Module Series WCDMA UGxx Audio Design Note Figure 11: Five Echo Paths In these five paths, internal air-path and direct air-path are the first influential factors. Other three factors (vibrations through casework, vibrations through PCB, distant echoes) are secondary. To deal with echo issue from internal air-path, you can separate microphone from internal space of chassis by foam or rubber ring which can effectively suppress the inner echo interference.

  • Page 21: Component Of Spk

    UMTS/HSPA Module Series WCDMA UGxx Audio Design Note NOTE The best installation way of microphone socket is to encase microphone by silicone cover except for front cavity, and design a cylindrical hole whose center is the exit hole inside the chassis, make the microphone with silicone cover just fit the cylindrical hole, so as to only let voice enter into microphone from the exit hole, and not from leak of chassis interior.
