4-Channel PCM CODEC, 5.0V

The 821004 is a single-chip, four channel PCM CODEC with on-chip filters. The device provides analog-to-digital and digital-to-analog conversions and supports both a-law and m-law companding. The digital filters in 821004 provides the necessary transmit and receive filtering for voice telephone circ • 4-channel CODEC with on-chip digital filters \n• Selectable A-law or μ-law companding \n• Master clock frequency selection: 2.048MHz, 4.096MHz or 8.192MHz • Internal timing automatically adjusted based on MCLK and frame sync signal ;
