AED-109 Dual Channel Daughterboard

DATA SHEET

Product Available Now

The SIGNALWARE AED-109 Dual-Channel Analog Expansion Daughterboard for the Texas Instruments TMS320C5x/6x evaluation products provides an economical way to build a fast feedback control system or data collection processor. The daughterboard has two 2-channel A/D converters and two D/A converters; the input channels may be paired to give 2 differential inputs simultaneously sampled. The D/A output channels may be updated simultaneously. Six buffer amplifier and 4 transformer positions provide a variety of input-output and signal conditioning options. In addition to analog channels, 16 buffered digital signals are available in two configurations. Breadboard space provides for signal conditioning and interface circuits. The AED-109 has application in image sensor processing, communications, and feedback control.

The AED-109 is ideally suited to prototyping systems with TI C5x and C6x Digital Signal Processors (DSP). A wide variety of TI DSP devices can be evaluated or demonstrated by combining TI prototyping products with this daughterboard. The analog circuit prototyping for signal conditioning is conveniently built with specialized analog and breadboard areas on the daughterboard. The digital interface to the DSP is accomplished with a Field Programmable Gate Array (FPGA). This approach to prototyping can significantly reduce time to market.

Also, the AED-109 may be used to construct inexpensive personal computer based or standalone systems where the number of systems does not justify a custom designed board. Test equipment and instrumentation are examples of low volume DSP applications.

The standard AED-109 consists of a daughterboard for the expansion interface on the C5x or C6x Evaluation Modules or DSP Starter Kits. The standard full size daughter board configuration includes 2-A/D, 2-D/A, voltage reference, 16 digital I/O, regulators, programmable logic interface, a 40-pin digital I/O connector, and four SMB RF connectors for off-board connections. Additional options include analog buffers, transformers, four more SMB connectors, and flash memory for DSP program storage available in either 512 Kbyte or 1 Mbyte. The digital I/O may be configured as: 4 input, 4 output and a group of 8 that can be switched to either input or output, or as two switchable groups of 8. The AED-109 comes with a demonstration logic program and test software for the DSP.

Programmable DSP I/F Adds Performance

Preprocessing of the A/D samples and control of the converters with the FPGA significantly reduces the load on the DSP making more computation possible with the DSP. A Xilinx Spartan^TM XCS20 FPGA with approximately 20,000 logic gates is standard, and larger Virtex-E^TM FPGAs are available as options. Socketed, serial PROM or optional serial flash memory provide FPGA configuration.

Surface Mount Breadboard Adds Flexibility

To make the analog interface to the A/D and D/A converters convenient and flexible, 7 square inches of breadboard space for surface mount and through-hole analog ICs is provided. The AED-109 breadboard accommodates wide and narrow SOIC (50 mil pitch) packages as well as 0.3 and 0.6 DIPs (100 mil pitch). By keeping the application specific signal conditioning circuits on the board with the converters, noise, errors, and cost are reduced. The breadboard area is supplied with regulated +/- DC analog power voltages, and 4.096, 2.048 and 1.024 reference voltages.
