Page 4: Overview
Overview www.ti.com Overview The ADS9224REVM-PDK is an evaluation platform for the ADS9224R, a dual, simultaneous-sampling, 16- bit, 3-MSPS, fully-differential input successive approximation register (SAR) analog-to-digital converter (ADC). The ADS9224R features an enhanced serial multiSPI™ digital interface. The evaluation kit includes the ADS9224REVM board and the Precision Host Interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC using a USB interface for data capture and analysis.

The SDO Mode drop-down menu allows selection between standard SPI and multiSPI modes. The ADS9224REVM-PDK software supports maximum throughput of 3-MSPS when using Dual- and Quad- SDO lanes, and a maximum throughput of 2.61-MSPS when using Single-SDO lane. For maximum throughput of 3-MSPS, select the Dual or Quad-SDO lanes.
