2. Our Design A portable, single-cable, USB design that allows digital playing and recording of FM radio on a PC

3. FM Module Uses Philips TEA5757 FM Receiver Highly Integrated – Eliminating Most External Analog Components 3 lines for control (clk, data, write enable) Provides Analog Stereo Output Tunes To Frequencies On The FM Band (87 MHz – 108 MHz) Tuning, Detection and Demodulation Are Handled Internal to the IC

4. USB Module Features UDA1325 USB Microcontroller Supports USB Protocols Versions 1.0 and 2.0 Built-in ADC for Audio Applications Low Current Consumption Configurable Via External EEPROM

5. Software Interface Programmed using DirectX 8.1b in Visual C++ Controls the FM Receiver via the Universal Serial Bus Streams PCM audio data from the USB controller to the PC audio hardware Provides support for digital frequency tuning and searching

7. Lessons Learned Choose an advisor with experience with your project’s technology Ensure technical help before designing with a product Limit SMT components; board modifications are more difficult Limit complexity of the project because it will always get harder Datasheets are not always correct Outsource when you can; it’s only money Keep your advisor happy Start early and work hard Keep thorough lab notes

8. Packaging Project designed using SMT components Professionally manufactured PCBs Boards mounted directly to packaging
