WM9714L AC’97 Audio Codec DESCRIPTION FEATURES The WM9714L is a highly integrated input/output device designed for mobile computing and communications. The chip is architected for dual CODEC operation, supporting hifi stereo CODEC functions via the AC link interface, and additionally supporting voice CODEC functions via a PCM type Synchronous Serial Port (SSP). A third, auxiliary DAC is provided which may be used to support generation of supervisory tones, or ring-tones at different sample rates to the main CODEC. The device can connect directly to mono or stereo microphones, stereo headphones and a stereo speaker, reducing total component count in the system. Cap-less connections to the headphones, speakers, and earpiece may be used, saving cost and board area.
