Product Summary
The WM9714G is a highly integrated input/output device designed for mobile computing and communications. The WM9714G is architected for dual CODEC operation, supporting Hi-Fi 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 applications of the WM9714G are Personal Digital Assistants (PDA) with or without phone, Smartphones and Handheld and Tablet Computers.
