系统与换能器连接的物理层，实现换能器的驱动以及阻抗匹配，如下图6。TI的USS模块提供双路换能驱动以及信号接收。驱动信号和接收信号通过模拟开关切换实现上、下行换能器的交换，实现一对换能器可以双向信号传输。PHY的输出驱动阻抗可以低至4Ω、驱动电流可以高达120mA，所以配合简单的阻容电路，USS模块可以直接驱动换能器，而不需要增加额外的模拟器件。

因为上、下行超声波信号会通过两个不同的换能器发出，换能器与USS驱动的阻抗匹配就需要考虑到。TI USS的PHY可以提供驱动、端接两种状态下的阻抗匹配，匹配设定参数可以保存在寄存器里面。这样在生产的过程中，我们可以通过自动测试设备对每一个换能器进行独立阻抗匹配，使整个系统达到优状态。
