语音和音频编解码器

WM9714 是一款高度集成的输入/输出设备，专为移动计算和通信而设计。此芯片架构支持双编解码器操作，通过 AC 链路接口支持高保真立体声编解码器功能，此外还通过脉冲编码调制 (PCM) 型同步串行端口 (SSP) 支持语音编解码器功能。提供第三款辅助数模转换器 (DAC)，可用于支持以不同于主编解码器的采样率生成检测音或铃音等。此器件可直接连接到单声道或立体声麦克风、立体声耳机和立体声扬声器，从而减少系统中的组件总数。可以使用耳机、扬声器及听筒的无电容连接，从而节省成本和电路板空间。此外，还提供多路模拟输入和输出引脚，以便与模拟连接的无线通信设备无缝集成。所有器件功能都可通过符合 AC97 ·兼容 AC 97 版本 2.2 的立体声编解码器\n·数模转换器 (DAC) 信噪比 (SNR) 94 dB, 总谐波失真 (THD) –85 dB\n·模数转换器 (ADC) 信噪比 (SNR) 87 dB, 总谐波失真 (THD) –86 dB\n·可变速率音频，支持所有 WinCE 采样率\n·音调控制、低音增强和 3D 增强\n·片上 45 mW 耳机驱动器\n·片上 400 mW 单声道或立体声扬声器驱动器\n·立体声、单声道或差分麦克风输入\n·自动电平控制 (ALC)\n·麦克风插入和按钮检测\n·辅助单声道数模转换器 (DAC)（生成铃声或直流电平）\n·与无线芯片组的无缝接;
