FREQUENCYDEVICES SPP-01S

SPP-01 Series
2” X 2” Precision
Hardware Solution
Dual Channel, Differential Input
Signal Processing Platform
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 SPP01 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.
