DSPxThe DSPx is a fully wired and tested Digital Signal Processing (DSP) Module suitable for DSP development and learning, as well as embedding into your own projects.
The DSPx is fully compatible with the W7PUA DSP-10 2-meter Software Defined Radio.
The DSPx is interfaced to the DSP-10 with the KDSP10 Interface Adapter.
The DSPx module uses the Analog Devices ADSP-2185N Digital Signal Processor chip. It currently is equipped with a 4M bit/512k byte Flash memory, SST 39VF040 --> --> or similar. The product currently shipping includes a monitor that is compatible with the ADSP-2181 EZ Kit Lite
- Low Power: 225 mW
- Processing Speed: 80 MIPS
- Sampling Rate: 96 kHz
- 10 dB Greater Dynamic Range
- FLASH Memory
- Lots of Amateur Radio Source code
- DOS development tools
KDSP10 Interface Adapter Kit
- about 6-10 dB lower noise floor on the ADC, providing about 6-10 dB greater receiver dynamic range
- about 3 dB stronger output on the DAC
- much lower power consumption - you don't need to add an extra 9-V regulator
- direct support of Fast PTT
- smaller size
- more than twice the processing power, allowing development of even more features in the DSP-10
- FLASH rather than EPROM based
The KDSP10 also may be used to host the DSPx as a standalone developement platform.
Sorry, DSPx&KDSP10 set is no longer available
plus KDSP10 are also very useful as a DSP learning platform.
You can perform experiments in the new ARRL publication
Methods in RF Design
, Chapters 10 and 11. Code examples are available on the
KK7P EMRFD web
Current information and documentation is available at the KK7P DSPx web page.
TAPR kits can be complex depending on the kitting experience of each builder. We don't think you will have trouble with the DSPx or KDSP10 kit, but it does require some knowledge and experience to successfully go from a kit to a finished, usable unit, depending on the mode of operations.
