The ADC-PHI-PRU-EVM adapter card interfaces the development platforms of the Sitara™ processor for the AM64x family (TMDS64GPEVM) or the microcontroller (MCU) for the AM243x family (TMDS243GPEVM) to more than 25 precision analog-to-digital converter (ADC) evaluation modules (EVMs) for communication, data capture and software development.
ADC-PHI-PRU-EVM routes the ISSG-PRU signals to the corresponding serial peripheral interface (SPI) and enhanced SPI (eSPI) or parallel ADC data communication interfaces. The adapter card offers configurability through two jumpers that select between serial or parallel connections, and also offers a user-selectable power- and signal-level conversion to match the required digital and analog supply-voltage levels of the precision ADC EVM.
The programmability of the Sitara processor ICSSG-PRU peripheral allows for high-speed data capture along with data preprocessing. Users can eliminate the extra MCU or field-programmable gate array (FPGA) on the board of their current design and start system precision ADC and AM64x and AM243x software development with the ADC-PHI-PRU-EVM.
