3.6.4 Audio Section
1. Receive audio signal from microphone. C1150 use differential configuration.
2. Send audio signal to speaker. C1150 use differential configuration.
3. This section provides an audio codec with a digital-to-analog converter and an analog-to-
digital converter, a ring tone volume controller, a microphone interface, and multiple
analog input and output channels.
4. It interconnect with external device like main microphone, main receiver, and headset
jack through the AIN1N, AIN1P, AIN2N, AIN2P, AIN3N,AIN3P,AOUT1P,AOUT1N,
OUT2P,AOUT2N,AOUT3P, and AOUT3N port.
• AIN1P,AIN1N : Main microphone positive/negative terminal
• AOUT2P,AOUT2N : Main Speaker positive/negative terminal
• AIN2P,AIN2N : Ear-Mic microphone positive/negative terminal
• AOUT1P,AOUT1N : Ear-Mic speaker positive/negative terminal
