概要

DAC38RFxxは高性能、デュアル/シングル・チャネル、14ビット、9GSPS、RFサンプリングのデジタル/アナログ・コンバータ(DAC)のファミリで、0~4.5GHzの広帯域の信号を合成できます。DAC38RFxxファミリはダイナミック・レンジが広いため、ワイヤレス基地局やレーダー用の3G/4G信号など、広範なアプリケーション用の信号を生成できます。

このデバイスには低消費電力のJESD204Bインターフェイスが搭載され、8つまでのレーンで最大12.5Gbpsのビット速度をサポートするため、チャネルごとに1.25GSPSの複素数データを入力できます。DAC38RFxxにはチャネルごとに2つのデジタル・アップ・コンバータが搭載されており、複数の補間レート・オプションを選択できます。独立した、柔軟な周波数を選択できるNCOを持つ、デジタル直交変調器が利用可能で、マルチ・バンドの動作に対応できます。オプションの低ジッタPLL/VCOにより、低い周波数の基準クロックを使用できるため、DACサンプリング・クロックの生成が簡単になります。
