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 Channel Associated Signaling
§ Each channel can be independently idled or
placed into bypass
§ Available hardware mode requires no host
processor; ideal for voice storage
applications
§ Single +5V supply; low-power CMOS
technology
§ Available in 28-pin PLCC
§ 3V operation version is available

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 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 follows the algorithm specified by CCITT
Recommendation G.721 (July 1986) and ANSI document T1.301 (April 1987). The compression to
24kbps follows ANSI document T1.303. The compression to 16kbps follows a proprietary algorithm
developed by Dallas Semiconductor. The DS2165Q can switch compression algorithms on-the-fly. This
allows the user to make maximum use of the available bandwidth on a dynamic basis.
