WM8802
Digital Audio Interface Transceiver
DESCRIPTION
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.
