    Introduction 1 Introduction ™ The ADC-PHI-PRU-EVM evaluation adapter card interfaces the Sitara AM64x processor (TMDS64GPEVM) or AM243x MCU (TMDS243GPEVM) development platforms to greater than 25 precision ADC EVMs for communication, data capture, and software development. The adapter card routes the ICSSG-PRU signals to the corresponding serial (SPI and eSPI) or parallel ADC data communication interfaces.

    2 ADC-PHI-PRU-EVM Overview Figure 2-1 shows the two main connectors of the ADC-PHI-PRU-EVM adapter card. The 150-pin high-speed expansion (HSE) connector is on the left and mates with the AM64x and AM243x general purpose (GP) development platform HSE connectors. The 60-pin Q-strip (QSH) connector is on the right and mates with the...

    The PA007 board outputs 5.5 V, which is commonly used for the analog supplies, and either 3.3 V or 1.8 V for digital, I/O, and EEPROM supplies. To match the supply voltages, the ADC-PHI-PRU-EVM converts and routes the 5-V, 3.3-V, and 1.8-V supplies that are featured on the HSE connector to the QSH connector.
