DSP56009 Evaluation Module

The DSP56009 Evaluation Module is a low-cost platform for multichannel digital audio applications development and prototyping. It demonstrates the capabilities and features of Motorola's DSP Symphony^®™ family of audio products, which include the DSP56004, the DSP56004ROM, the DSP56007, and the DSP56009. The DSP56009EVM features a DSP56009 with embedded software (including FFTs, FIR filters, and IIR filters) that is useful in a variety of user-developed audio software.

The DSP56009EVM is intended to provide a turnkey solution for digital audio decoding in audio/video applications, such as stereos and television sets. It provides full support for Dolby Pro Logic® and Dolby Digital AC-3™ embedded in software.

This Evaluation Module is a complete system with high quality stereo Analog-to-Digital (A/D) conversion and six channels of Digital-to-Analog (D/A) conversion. The onboard circuitry includes a microcontroller, RS-232-to-On-Chip Emulation (OnCE™ ) port debug interface, LCD display, memory, and digital audio Input/Output (I/O). The user only needs to supply a dual 8 to 12 volt power supply for analog circuits, an 8 to 15 volt power supply for digital circuits, and an RS-232 serial cable.

The DSP56009EVM also includes Motorola's DSP56000 cross-linker Assembler and Domain Technologies' Debug-56K debugging software, which runs under Microsoft® Windows™ 3.1 and Windows™ 95 on IBM PC-compatible computers (386 class or higher) and communicates with the Evaluation Module via an RS-232 serial port.
