TUSB211は、USBハイ・スピード(HS)信号コンディショナーで、伝送チャネルでのISI信号損失を補償するよう設計されています。
デバイスには特許取得の設計が採用されており、USB Low Speed (LS)とFull Speed (FS)のどちらの信号でも関係なく動作します。LSおよびFS信号の特性は、TUSB211により影響を受けません。HS信号は補償されます。
信号ゲインをプログラム可能で、コネクタでHigh Speed信号を最適化するようデバイスの性能を微調整できます。この機能は、USB High Speedの電気コンプライアンス・テストに合格するため役立ちます。
TUSB211の占有面積は、DP/DM信号パスの連続性を分断しません。このため、完全なUSBチャネルのシステムをリスクフリーで設計できます。
さらに、TUSB211はUSB On-The-Go (OTG)やBattery Charging (BC)プロトコルとも互換性があります。
