TIDA-00431 — 採用 8 GHz DC 耦合差動放大器的射頻取樣 4 GSPS ADC 參考設計

寬頻射頻 (RF) 接收器可大幅提高無線電設計的靈活性。寬廣的瞬時頻寬允許在不更換硬體的情況下進行靈活調諧,並能夠擷取頻率相差很大的多個通道。

此參考設計說明了一種寬頻 RF 接收器,它採用 4GSPS 類比數位轉換器 (ADC),並具有 8GHz DC 耦合全差動放大器前端。放大器前端提供訊號增益,並允許擷取低至 DC 的訊號。這是使用平衡不平衡轉換器耦合輸入時無法實現的。

TIDA-00432 — 使用適用於相位陣列雷達系統的 Xilinx 平台,將 JESD204B Giga-Sample ADC 同步化

此系統級設計展示如何使用 Xilinx VC707 平台將兩個 ADC12J4000 評估模組 (EVM) 同步在一起。設計文檔描述了所需的硬體修改和設備配置,包括時脈方案。每個 EVM 都提供了範例設定檔案。本文描述了 FPGA 韌體,並展示了相關的 Xilinx IP 模組配置參數。對實際硬體上採集的數據進行展示和分析,結果表明,在沒有對電纜進行特徵分析或校準傳播延遲的情況下,同步時間在 50ps 以內。
