6.3.1.3 Using Multiple Devices With Shared Buses

The device has many supported features and flexible options that can be used in the system to seamlessly connect the TAA3020 and any other audio device by sharing a single common I2C control bus and an audio serial interface bus. This architecture enables multiple applications to be applied to a system that require a microphone array for beam-forming operations, audio conferencing, noise cancellation, and so forth. Figure 6-13 shows a diagram of the TAA3020 and TLV320ADCx140 devices in a configuration where the control and audio data buses are shared.

TAA3020 Multiple Devices With Shared Control and Audio Data Buses Figure 6-13 Multiple Devices With Shared Control and Audio Data Buses

The TAA3020 consists of the following features to enable seamless connection and interaction of multiple devices using a shared bus:

  • I2C broadcast simultaneously writes to (or triggers) all TAA3020 and TLV320ADCx140 devices
  • Supports up to 64 configuration output channel slots for the audio serial interface
  • Tri-state feature (with enable and disable) for the unused audio data slots of the device
  • Supports a bus-holder feature (with enable and disable) to keep the last driven value on the audio bus
  • The GPIO1 or GPOx pin can be configured as a secondary output data lane for the audio serial interface
  • The GPIO1 or GPIx pin can be used in a daisy-chain configuration of multiple devices
  • Supports one BCLK cycle data latching timing to relax the timing requirement for the high-speed interface
  • Programmable master and slave options for the audio serial interface
  • Ability to synchronize the multiple devices for the simultaneous sampling requirement across devices
See the Multiple TLV320ADCx140 Devices With Shared TDM and I2C Bus application report for further details.
