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 compression at three different rates. The chip can be programmed to compress (expand) 64kbps voice data down to (up from) either 32kbps, 24kbps, or 16kbps. The compression to 32kbps.
§ § 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 Channel Associated Signaling Each channel can be independently idled or placed into bypass Available hardware.
