Description

The WM8803 is a digital audio interface receiver conforming to IEC 60958/61937 and EIAJ CP-1201. It supports input audio data rates up to 192kHz and a maximum output data length of 24 bits.

The WM8803 has a flexible digital output port that allows the user access to channel status pre-emphasis information, input signal sampling frequency, sub-code Q data with the associated CRC flags and other status data.

The WM8803 can output an externally input clock signal that can be used as an ADC converter clock when the PLL is unlocked. It also maintains the continuity of the output clock when the clock is switched.

The WM8803 includes a built-in oscillator and serial data input circuits and allows the system micro-controller to read the sub-code Q data and the channel status. It provides several low-power modes, thus supporting applications that require long battery life, such as portable audio devices and PDAs.

The device is available in a 24-pin TSSOP package.
