マキシムは、セットトップボックスアプリケーション用に画期的かつ低電力のSCARTスイッチを提供しています。
超低電力
マキシムの最新SCART製品のオーディオおよびビデオ回路は、競合製品のような5Vおよび12Vではなくすべて3.3Vで動作します。マキシムのSCART ICの特長は以下です。
- CVBS入力のアクティビティを検出
- CVBS出力の負荷とスロースイッチ信号レベルを検出
- I²Cを使って、マイクロコントローラにその他コンポーネントのパワーアップ/ダウンを伝達
オーディオのクリック&ポップのノイズを除去するDirectDrive®
DirectDriveにより、STBがパワーアップされていてもパワーダウンされていてもオーディオライン出力のDCバイアスは常にグランドにあります。
単一電源で動作する従来のオーディオライン出力ドライバはシリーズAC結合コンデンサが必要です。パワーアップ/ダウン時、このコンデンサのDCバイアスはグランドと正電圧間で動き可聴トランジェントを生成します。
