2” X 2” Precision Dual Channel, Differential Input Hardware Solution Signal Processing Platform 25 Locust St., Haverhill, Massachusetts 01830 • Tel: 800/252-7074, 978/374-0761 • FAX:978/521-1839 e-mail: sales@freqdev.com • Web Address: http://www.freqdev.com Design engineers now have a precision dual channel hardware solution that acts as it s own evaluation board to facilitate algorithm development. After the unit is programmed, SPP-01’s can be directly inserted int o productio n applicat ions as a f inished subassembly, minimizing product development time and space while shortening manufacturing cycle-time and providing repeatability.

Description

The SPP-0 1 Series of Signal Pro cessing Platforms are progra mmable over a 20 kHz audio fre quency range and o ffer 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 pr ocessing with THD approaching –100 dB. The fixed point DSP utilize s 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 allo ws the emulator to communicate with the SPP-01 hardware. Designers can directly load algorithms into the SPP- 01 via the RS232 i nterface on the SPPDB-01 development board. Features/ Benefits:

  • Compact 2” x 2” dual channel de sign combin ed with large program memory (256 k EE-Pro m) and

4 Mbits of flash memory opti mizes your DSP

processing power in minimal board space.

  • Socketed SPPDB-01 development hardware offers rapid set-up, programming and performance evaluation, shortening the product developme nt cycle while insuring high precision field installation.
  • Analog inpu ts, storage for 100’s of standard o r customer application specific algorithms, and analog or digital outp uts, provides unmatched flexibility for design and implementation.
  • For multi-ch annel applications, d esign engine ers can have phase synchronous operation by providing an external buffer to the SLAVE clock input.
