TIDA-010191 — 航太級多通道 JESD204B 15-GHz 時脈參考設計

相位陣列天線和數位波束成形技術，是提高未來航太雷達成像和寬頻衛星通訊系統的性能的關鍵技術。數位波束成形與類比波束成形不同，通常每個天線元件需要一套資料轉換器。這些轉換器需要具有具體定義相位關係的時鐘。此參考設計展示如何透過已定義及可調整相位關係，產生低雜訊 MHz 至 GHz 時脈訊號。在發生單一事件後，甚至可能恢復時脈階段。透過操作兩個 ADC12DJ3200QML-SP 評估模組，及在 3.2 GHz 時其對應之 FPGA 架構擷取平台，以及 10-ps 板對板偏斜的情況，藉此來展示 JESD204B 支援。
