简  介:w 5 to 7.1 Channel PWM Controller DESCRIPTION The WM8608 comprises a high performance multi-channel PWM digital power amplifier controller. Simply by adding appropriate power output stages a multi-channel power amplifier may be built. Six identical full audio bandwidth channels, plus a reduced bandwidth sub channel are provided as PWM outputs, to drive 6 speakers plus Sub. The PCM to PWM converter supports up to 7.1 channels of audio, in PCM input formats. These may be mixed down to 6.1 or 5.1 outputs, by mixing rear channel data into centre rear or surround speakers if required. If 5.1 channel data is input, the surround data may be processed internally to create a pseudo 6.1 signal with rear channel output. A Graphic Equaliser function is provided, plus selectable high frequency equalisation to suit different speaker types. Independent volume control for each channel is provided. The WM8608 PWM controller is compatible with integrated switching output stages available from a number of vendors or alternatively may be used with a discrete output stage configuration and achieve similar levels of performance. A Dynamic Peak Compressor with programmable attack and decay times is included, which allows headroom for tone control, bass management and extra digital gain to be provided, without clipping occurring. A Synchroniser allows slaving to LRCLK, thus making the WM8608 independent of source MCLK frequency and jitter. The device is controlled via a 2/3 wire serial interface. Th……
