Description of the Application Interfaces

The two audio I/O channels are completely different and thus have good performance of resisting RF interferences. The routes on the printed circuit board (PCB) should be placed in parallel with each other and should be short. The filter circuit on the two sides should be symmetric. The differential signals should be close to each other. The audio output signals in differential pairs and the audio input signals in differential pairs should be separated effectively through ground. In addition, the audio signals should be located away from the circuits of the power supply, RF, and antenna.

The first audio channel can be used for the handset without requiring any audio amplifier. The output power for the differential ear output is typically 350mW for a full- scale +3dBm sine wave into a 32-ohm speaker.

The second audio channel can be used for the hands-free without requiring any audio amplifier. The output pins are configured differently, with a rated output of 500 mW into an 8Ω speaker. Considerable current flows between the audio output pins and the speaker, and thus wide PCB traces are recommended (20mils).

MC509 provides 2.2V power source and 1mA of bias current internally for the microphones of both audio channels.
