Design engineers now have a precision dual channel

hardware solution that acts as its own evaluation

board to facilitate algorithm development.

After the unit is programmed, SPP-01’s can be directly

inserted into production applications as a finished

subassembly, minimizing product development time

and space while shortening manufacturing cycle-time

and providing repeatability

.

Description

The SPP-01 Series of Signal Processing Platforms

are programmable over a 20 kHz audio frequency

range and offer up to 9-bits of addressing. This dual

channel DSP design and development solution, in a 2”

x 2” footprint, contains anti-alias filters, reconstruction

filters, ADC’s and DAC’s sampling at 48 kHz. SPP-01

platforms are small subassemblies that provide low

noise and distortion signal processing with THD

approaching –100 dB.

The fixed point DSP utilizes

32-bit math to achieve 24-bits of precision.

SPP-01’s can be programmed with standard or

customer specific algorithms.

Algorithms are easily

verified via an on-board JTAG port that allows the

emulator to communicate with the SPP-01 hardware.

Designers can directly load algorithms into the SPP-

01 via the RS232 interface on the SPPDB-01

development board.

Features/ Benefits:

• Compact 2” x 2” dual channel design combined

with large program memory (256 k EE-Prom) and

4 Mbits of flash memory optimizes your DSP

processing power in minimal board space.

• Socketed SPPDB-01 development hardware

offers rapid set-up, programming and performance

evaluation, shortening the product development

cycle while insuring high precision field installation.

• Analog inputs, storage for 100’s of standard or

customer

application

specific

algorithms,

and

analog or digital outputs, provides unmatched

flexibility for design and implementation.

• For multi-channel applications, design engineers

can

have

phase

synchronous

operation

by

providing an external buffer to the SLAVE clock

input.
