DESCRIPTION
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, 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 a 4-wire or 5-wire touchpanel, 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 analog input and output pins are provided for seamless integration with analog 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 masterclock 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 WM9713L 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.

DESCRIPTION
The WM9715L is a highly integrated input / output device designed for mobile computing and communications. The device can connect directly to a 4-wire or 5-wire touchpanel, mono or stereo microphones, stereo headphones and a mono speaker, reducing total component count in the system. Additionally, phone input and output pins are provided for seamless integration with wireless communication devices.
The WM9715L also offers up to four auxiliary ADC inputs for analogue measurements such as temperature or light. To monitor the battery voltage in portable systems, the WM9715L has two uncommitted comparator inputs.
All device functions are accessed and controlled through a single AC-Link interface compatible with the AC’97 standard (rev 2.2). Additionally, the WM9715L can generate interrupts to indicate pen down, pen up, availability of touchpanel data, low battery, and dead battery.
The WM9715L 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 handheld portable systems.
