系統(tǒng)與換能器連接的物理層，實現(xiàn)換能器的驅動以及阻抗匹配，如下圖6。TI的USS模塊提供雙路換能驅動以及信號接收。驅動信號和接收信號通過模擬開關切換實現(xiàn)上、下行換能器的交換，實現(xiàn)一對換能器可以雙向信號傳輸。PHY的輸出驅動阻抗可以低至4?、驅動電流可以高達120mA，所以配合簡單的阻容電路，USS模塊可以直接驅動換能器，而不需要增加額外的模擬器件。

因為上、下行超聲波信號會通過兩個不同的換能器發(fā)出，換能器與USS驅動的阻抗匹配就需要考慮到。TI USS的PHY可以提供驅動、端接兩種狀態(tài)下的阻抗匹配，匹配設定參數(shù)可以保存在寄存器里面。這樣在生產的過程中，我們可以通過自動測試設備對每一個換能器進行獨立阻抗匹配，使整個系統(tǒng)達到優(yōu)狀態(tài)。
