SPPDM-01

• Compact 2" x 2" dual channel design combined with large program memory (256 k EE-Prom) and 4-Mbits of flash  emory optimizes DSP processing power in minimal board space.
• SPPDB-01 development hardware offers rapid set-up, programming and performance evaluation, shortening the product development cycle while insuring high precision field programmable installation.
• Field programmability of coefficient sets, analog I/O and storage for 100's of application specific FIR filters provide  esigners with unmatched design, implementation and field upgrade flexibility.

• Brick-Wall; High-Pass, Low-Pass, Band-Pass, Band-Reject and Multi-Rate filters with Linear Phase and Signal Generators for Data Acquisition Systems.
• Speech analysis, research, pathology
• Sound and vibration testing

Design engineers now have an off-the-shelf precision, dual channel hardware solution for development of digital FIR filters that can be used in production subassemblies. Designers can generate FIR filter characteristics in a MatLabTM V5.3 or V6.0 environment and directly load standard or custom coefficient sets into the SPPDM-01 platform via an RS232 interface located on the users field programmable subassembly or from the SPPDB-01 development board.

By utilizing the SPPDF-01 hardware with the enclosed MatLab GUI, generated coefficients are loaded directly into the removable SPPDM-01 platform for insertion into finished EOEM products. This unique capability minimizes product development and manufacturing cycle times while providing precise unit-to-unit product matching in a small 2" x 2" footprint that can be reconfigured or upgraded in the field.

SPPDM-01 FIR filter platforms operates over a 100 Hz to 20 kHz audio frequency range. Each channel can be configured to provide up to 9-bits of filter frequency programmability per channel. This dual channel DSP design solution contains anti-alias and reconstruction filters along with ADC's and DAC's offering low noise and distortion signal processing with THD approaching 100 dB. Sampling at 48 kHz the fixed point DSP utilizes 32-bit math to achieve 24-bits of precision.
