QUAD NON-PROGRAMMABLE PCM CODEC Features - - - IDT821024 DESCRIPTION The IDT821024 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 µ- law panding. 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. In the IDT821024 the PCM data is transmitted to and...
