DS2165/DS2165Q
022698 1/18
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 375
μ
s
Simple serial port used to configure the device
Onboard 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
Backward-compatible with the DS2167 ADPCM
Processor Chip
Single +5V supply; low-power CMOS technology
Available in 24-pin DIP and 28-pin PLCC

DESCRIPTION
The DS2165 ADPCM Processor Chip is a dedicated
Digital Signal Processing (DSP) chip that has been opti-
mized to perform Adaptive Differential Pulse Code Mod-
ulation (ADPCM) speech compression at three different
rates. The chip can be programmed to compress (ex-
pand) 64Kbps voice data down to (up from) either
32Kbps, 24Kbps, or 16Kbps. The compression to
32Kbps follows the algorithm specified by CCITT Rec-
ommendation G.721 (July 1986) and ANSI document
T1.301 (April 1987). The compression to 24Kbps fol-
lows ANSI document T1.303. The compression to
16Kbps follows a proprietary algorithm developed by
Dallas Semiconductor. The DS2165 can switch com-
pression algorithms on-the-fly. This allows the user to
make maximum use of the available bandwidth on a dy-
namic basis.
