30 / 52 page  Smart Machine Smart Decision SIM800C_Hardware_Design_V1.02 30 2015-4-27 In order to improve audio performance, the following reference circuits are recommended. The audio signals have to be layout according to differential signal layout rules as shown in following figures. 4.7.1. Speaker Interfaces Configuration SP KP Close to speaker ES D ESD 10pF 33pF 33pF 33pF M odule S PKN 10pF 10pF 10pF 33pF 33pF 33pF 10pF 10pF Figure 28: Speaker reference circuit 4.7.2. Microphone Interfaces Configuration Electret Microphone The lines in bold type should be accorded to differential signal layout rules These components should be placed to microphone as close as possible MIC P M odule MIC N ESD ESD 10pF 33pF 33pF 33pF 10pF 10pF Figure 29: Microphone reference circuit 4.7.3. Audio Electronic Characteristic Table 13: Microphone input characteristics Parameter Min Typ Max Unit Microphone biasing voltage - 1.9 2.2 V Working current - - 2.0 mA Input impedance(differential) 13 20 27 KΩ Idle channel noise - - -67 dBm0 SINAD Input level:-40dBm0 29 - - dB |
