WM8802

w 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. FEATURES PLL circuit for synchronization with transferred input biphase mark signal. Input sampling frequency: 32kHz to 192kHz Outputs clocks: fs, fs/2, 2fs, 32fs, 64fs, 128fs, 256fs, 384fs, and 512fs. 4-Wire CCB MPU Serial Control or Hardware Default Interface Master or Slave Clocking Mode Programmable Audio Data Interface Modes − I2S, Left, Right Justified − 16/20/24/32 bit Word Lengths 3.3V Digital supply Operation 5V tolerant digital input ports APPLICATIONS DVD Receivers AV Amplifiers DVD Recorders BLOCK DIAGRAM RXOUT RX0 RX1 RX2 RX3 RX4 RX5/VI RX6/UI EMPH/UO AUDIO/VO W WM8802 CBIT, UBIT INPUT SELECTOR DEMODULATION AND LOCK DETECT INT CL CE DI XMODE MICROCONTROLLER I/F DATA SELECTOR ...
