The WM9713L is a highly integrated input/output device
designed for mobile computing and communications.
The chip 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 Aux
DAC is provided which may be used to support generation
of supervisory tones, or ring-tones etc. at different sample
rates to the main codec.
The device can connect directly to a 4-wire or 5-wire touch-
panel, mono or stereo microphones, stereo headphones
and a stereo speaker, reducing total component count in the
system.
Cap-less
connections
speakers, and earpiece may be used, saving cost and
board area. Additionally, multiple analog input and output
pins are provided for seamless integration with analog
connected wireless communication devices.
to
the
headphones,
All device functions are accessed and controlled through a
single AC-Link interface compliant with the AC’97 standard.
The 24.576 MHz masterclock can be input directly or
generated internally from a 13MHz (or other frequency)
clock by an onboard PLL. The PLL supports a wide range
of input clock from 2.048Mhz to 78.6Mhz.
The WM9713L operates at supply voltages from 1.8 to 3.6
Volts. 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.
