User’s Guide DAC12DL3200 Evaluation Module ABSTRACT The DAC12DL3200 evaluation module (EVM) is used to evaluate the DAC12DL3200 digital-to-analog converter (DAC) from Texas Instruments. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the DAC12DL3200EVM. Table of Contents Introduction.....................................2... -
Page 2: Introduction
Software GUI, is used to send LVDS data test patterns to the DAC12DL3200EVM. With proper hardware selection in the HSDC Pro software, the TSW14DL3200EVM is automatically configured to support the different modes of operation of the DAC12DL3200. The interface provides LVDS output data up to 1600 MSPS. -
Page 3: Low Latency Evaluation Of Receive And Transmit
ADC12DL3200 device and the samples are extracted and collected by the FPGA. These samples are then forwarded to the DAC12DL3200 which generates the resultant output signal (delayed version of the input test signal). The IO architecture of the Xilinx UltraScale enables extremely high-speed data rates by trading off latency for throughput. -

TSW14DL3200EVM User's Guide ADC12DL3200EVM User's Guide for configuration and status information. 2 Equipment This section describes the equipment needed to evaluate the full performance of the DAC12DL3200 device. 2.1 Evaluation Board Feature Identification Summary Figure 2-1 shows the EVM features. Note The EVM does not have any power sequencing as the EVM was designed before this requirement was added to the data sheet. -
Page 5: Required Equipment
By default, the DAC12DL3200EVM uses an external clocking solution. A few small board modifications enable the onboard clocking solution. If onboard clocking is used, no signal generators are required. SBAU374 – MAY 2021 DAC12DL3200 Evaluation Module Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated... -
