Features

  • Provides connection for the AM64x PRU and GPIO pins to the ADC interface for high-speed, flexible, data acquisition, and device configuration
  • 5.5-V boosted supply from the AM64x TMDS64GPEVM 5-V supply rail using the TPS61096A
  • Jumper configurable support for serial (SPI) and parallel data types (J9)
  • Precision ADC EVM DVDD voltages of 1.8 V and 3.3 V are available with jumper configuration (J11)
  • No external MCU or processing chip required to interface the TMDS64GPEVM and precision ADC EVM
