General Description

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 1986) and ANSI document T1.301 (April 1987).

Key Features

  • Compresses/expands 64kbps PCM voice to/from either 32kbps, 24kbps, or 16kbps Dual fully independent channel architecture; device can be programmed to perform either: - two expansions - two compressions - one expansion and one compression Interconnects directly to combo-codec devices Input to output delay is less than 375ms Simple serial port used to configure the device On-board time-slot assigner-circuit (TSAC) function allows data to be input/output at various time slots Supports C.
