Benefits

• Programmable PLL with oscillator enables

full speed operation from low-speed input

clocks or crystals

• User selectable power-down modes reduces

system power consumption

• On-chip ROM with application specific user

code lowers cost in high volume systems

• Up to 11 DMA channels operate in parallel

maximizes I/O throughput

• Efficient C/C++ compiler simplifies software

programming task

Applications

• Telephony

• Modems

• Private Branch Exchange (PBX)

• Voice over network

• Home gateways

• Integrated access devices

• Optical networking

• Data acquisition

• Industrial automation

The ADSP-219x series represent ADIs newest

generation of ADSP-2100 code-compatible,

fixed-point DSPs operating at 160 MHz. DSPs

in this series integrate a high level of system

interfaces to provide DSP developers with a

rapid upgrade path to higher performance and

lower system cost. The ADSP-219x DSP

peripheral set has been optimized for

Telephony applications by integrating three

multi-channel serial ports that support up to

128 TDM channels, a 16-bit parallel and 16-bit

host interface – this enables rapid deployment

of cost effective voice platforms. The DSPs

integrate up to 32K words of 24-bit program

memory RAM, 32K words of 16-bit data mem-

ory RAM, and 16K words of 24-bit ROM. The

ADSP-2191, ADSP-2195, and ADSP-2196 are

all pin-compatible allowing many possibilities

for system upgrades. Pin-to-pin compatibility

allows programmers to migrate to larger mem-

ory models to increase end-product functionali-

ty without hardware redesign.
