The 821024 is a single-chip, four channel PCM CODEC with onchip
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 IDT821024 provides the necessary transmit and receive filtering
for voice telephone circuit to interface with time-division multiplexed
systems. All of the digital filters are performed in digital signal processors
operating from an internal clock, which is derived from MCLK . The fixed
filters set the transmit and receive gain and frequency response.
