SPP-01 Series 2” X 2” Precision Hardware Solution 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.
