2.3 Theory of Operation For SM-USB-DIG Platform

Figure 2-4 shows the block diagram for the SM-USB-DIG Platform. This platform is a general-purpose data acquisition system used on other Texas Instruments evaluation modules. The details of the USB DIG Platform operation are included in a separate document (available for download at www.ti.com). The block diagram shown in Figure 2-4 gives a brief overview of the platform. The TUSB3210 is the primary control device for the SM-USB-DIG Platform.
