The WM8802 is a digital audio interface transceiver conforming to IEC 60958/61937 and EIAJ CP-1201. The device supports data sampling input rates of up to 192 kHz. Data input to the serial digital audio data input pin can also be modulated. The WM8802 features up to 6 data inputs and 1 data output. Data can be demodulated using the on-board PLL or with the use of an external clock source. The WM8802 is controlled via a 4-wire CCB compatible control interface. This interface provides access to the channel status bits. The WM8802 also provides a number of flag outputs including PCM data valid, de-emphasis, lock and IEC 61937, DTS-CD/LD detection. The device is available in a small 48-pin SQFP package.
The WM8802 is a digital audio interface transceiver that supports IEC 60958/61937 and EIAJ CP‑1201 standards. It provides multiple data inputs, a single data output, and programmable clocking modes, making it suitable for DVD receivers, amplifiers, and recorders.
The device is supplied in a 48‑pin SQFP package and includes detailed electrical characteristics, absolute maximum ratings, and recommended operating conditions for designers.
