DS2165Q Overview
The DS2165Q ADPCM processor chip is a dedicated digital-signal-processing (DSP) chip that has been optimized to perform adaptive-differential pulse-code modulation (ADPCM) speech pression at three different rates. The chip can be programmed to press (expand) 64kbps voice data down to (up from) either 32kbps, 24kbps, or 16kbps. The pression to 32kbps follows the algorithm specified by CCITT Remendation G.721 (July...
