40 / 156 page  ALC5642-VF Datasheet Multi-Channel Audio Hub/CODEC with embedded Voice DSP and SounzReal TM Digital Sound Effect 28 Rev. 0.93 7.7. Analog Audio Input Port The ALC5642 has two types analog input ports: microphone input and line input. IN1P/N The IN1P/N is a microphone type input port. The input port can be configured to differential input or single-ended input by MX-0D[7]. The microphone input port has its microphone bias and microphone boost. The low noise microphone bias can improve recording performance and enhance recording quality. Build-in short current detection scheme can be used for switch detection. Multi-steps microphone boost gain set by sel_bst1 (MX-0D[15:12]) is easy to use for microphone application. Pow_bst1 can be used to power down the MIC1 boost and pow_micbias1 can be used to power down the microphone bias 1. IN2P/N The IN2P/N is a dual type input port: microphone input and line input. Microphone input can be configured to differential input or single-ended input by MX-0E[6]. Multi-steps microphone boost gain set by sel_bst2 (MX-0E[11:8]) is easy to use for microphone application. Pow_bst2 can be used to power down the MIC2 boost. As line input, it has volume control for tuning by MX-0F[12:8] and MX-0F[4:0]. IN3P/N The IN3P/N is a microphone type input port. Microphone input can be configured to differential input or single-ended input by MX-0D[6]. Multi-steps microphone boost gain set by sel_bst3 (MX-0D[11:8]) is easy to use for microphone application. Pow_bst3 can be used to power down the MIC3 boost. The port is pin share with MONOP and MONON. If as IN3P/N port needs power down MONOP/N. And if as MONOP/N port needs power down IN3P/N. |
