Abstract

This user's guide describes the characteristics, operation, and use of the ADS9218EVM-PDK evaluation module (EVM) performance demonstration kit (PDK). This kit is an evaluation platform for the ADS9218, which is an 18-bit, 10-MSPS, fully differential input, successive approximation register (SAR) analog-to-digital converter (ADC) that features a low-voltage differential signaling (LVDS) digital interface. The EVM-PDK also includes an adapter printed circuit board (PCB) that facilitates connection to a standard FPGA mezzanine card (FMC) connecter used in many field-programmable gate array (FPGA) kits. The EVM-PDK eases the evaluation of the ADS9218 device with hardware, software, and computer connectivity through the universal serial bus (USB) interface. This user's guide includes complete circuit descriptions, schematic diagrams, and a bill of materials (BOM). Throughout this document, the terms demonstration kit, evaluation board, evaluation module, EVM, and EVM-PDK are synonymous with the ADS9218EVM-PDK.
