9.2.1.2 Detailed Design Procedure

  • Use Figure 9-1as a guide to integrate the hardware into the system.
  • Following the recommended component placement, schematic layout and routing given in Figure 9-7, integrate the device and its supporting components into the system PCB file.
  • Determining sample rate and master clock frequency is required when powering up the device because all internal timing is derived from the master clock. Refer to the Audio Clock Generation section to obtain more information on how to configure correctly the required clocks for the device.
  • As the TLV320AIC3104-Q1 is designed for low-power applications, when powered up, the device has several features powered down. A correct routing of the TLV320AIC3104-Q1 signals is achieved by a correct setting of the device registers, powering up the required stages of the device and configuring the internal switches to follow a desired route.
