Interfacing the TLC5510 Analog-to-Digital Converter to the TMS320C203 DSP

This application report is a summary of the application note titled Interfacing the TLC5510 Analog-to-Digital Converter to the TMS320C203 DSP (literature number SLAA029) that presents guidelines for interfacing the TI TLC5510 analog-to-digital converter (ADC) to the TI TMS320C203 DSP. The TLC5510 is a CMOS, 8-bit, 20 MSPS (megasamples per second) ADC utilizing a semi-flash architecture. The TLC5510 includes internal-reference resistors, a sample-and-hold circuit, and 8-bit parallel outputs with high-impendance mode. The use of an evaluation module (EVM) is recommended due to the sampling rate of the TLC5510. Typically, when the sampling rate of an ADC exceeds 1 or 2 MHz the board layout is critical to the performance of the ADC, and the use of a breadboard for evaluation is no longer suitable. Control-logic circuits are used to access the data bus.
