Guide to hardware design with TMS320F28xx, F28xxx DSCs

Keywords:analogue-to-digital converter  digital signal controllers  hardware design 

TMS320F28xx and F28xxx digital signal controllers (DSCs) include multiple complex peripherals running at fairly high-clock frequencies. They are commonly connected to low level analogue signals using an onboard analogue-to-digital converter (ADC). This application report is organised as a guide for system level hardware design, parts selection, and schematics design to board layout and helps in avoiding those hardware errors that become costly and time consuming when detected during the system level-debugging phase of the project, using the prototype of the custom board of the project. The issues related to clock generation, JTAG, power supply, interfacing of peripherals with special attention to analogue inputs to ADC, general-purpose input/output (GPIO) connections, testing and debug, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) considerations, etc., are discussed. Each section explains signal routing and layout tips.
