Xilinx K7-325+AD9144 多模式实测｜8 种 JESD204B 配置全覆盖验证
本帖最后由 mdyfpga 于 2026-5-6 11:39 编辑一、背景概述
AD9144 是 ADI 经典四通道16位、2.8GSPS高速DAC芯片，支持灵活的JESD204B接口配置，广泛应用于无线通信、精密仪器仪表、雷达信号生成、电子对抗等工业与军工场景。
本次我们基于Xilinx K7-325 自研FPGA开发板MP5620Xilinx Kintex-7高速信号处理学习板 + 自研AD9144功能模块AD9144-FMC-EBZ ADI数据转接板四通道数模转换器评估板子模块转换，完成多工况、多模式完整上板验证。验证板如图一所示：

二、实测目标
本次多种模式实测核心目标如下：
1. 验证硬件兼容性：实测确认自研AD9144模块可稳定适配主流FPGA平台，实现端到端完整高速数据链路传输；
2. 验证多场景适配能力：搭配多种JESD204B差异化配置，覆盖高低不同采样率、多/少通道、不同Lane资源组合的各类工程需求；
3. 验证信号输出性能：在多组工作参数下，持续测试波形纯净度、输出稳定性与频率调节能力，充分验证模块电源完整性、时序设计与高速信号质量；
4. 降低客户开发门槛：全部例程均经过上板实测落地，提供成熟工程参考与配置方案，帮助客户快速移植、缩短调试周期、加快项目落地。
三、上板效果
我们以K7-325为核心主控平台，依托标准JESD204B协议架构，搭配专属时钟链路与时序优化设计，全覆盖 “8种主流工作模式” 逐一完成上电调试、链路同步、波形采集实测。全面校验不同通道数量、Lane链路配置、采样率及插值倍率组合下的系统稳定性、协议兼容性与动态输出性能，为不同行业项目选型、方案快速移植提供可直接复用的工程参考。
下面为大家逐一展示8种工作模式的配置详情、验证要点及适用场景效果演示：
