DESCRIPTION
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. Additionally, multiple analogue input and output
pins are provided for seamless integration with analogue
connected wireless communication devices.
All device functions are accessed and controlled through a
single AC-Link interface compliant with the AC’97 standard. The
24.576 MHz master clock can be input directly or generated
internally from a 13MHz (or other frequency) clock by an on-chip
PLL. The PLL supports a wide range of input clock from
2.048MHz to 78.6MHz.
The WM9714L operates at supply voltages from 1.8V to 3.6V.
Each section of the chip can be powered down under software
control to save power. The device is available in a small
leadless 7x7mm QFN package, ideal for use in hand-held
portable systems.
