7.3.1.3 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 multiple TAC5112 devices by sharing a single common I2C or SPI control bus and an audio serial interface bus. This architecture enables multiple applications to be applied to a system that require a microphone or speaker array for beam-forming operation, audio conferencing, noise cancellation, and so forth. Figure 7-14 shows a diagram of multiple TAC5112 devices in a configuration where the control and audio data buses are shared.

TAC5112 Multiple TAC5112 Devices With Shared Control and Audio Data Buses Figure 7-14 Multiple TAC5112 Devices With Shared Control and Audio Data Buses

The TAC5112 consists of the following features to enable seamless connection and interaction of multiple devices using a shared bus:

  • Supports up to four pin-programmable I2C target addresses
  • I2C broadcast simultaneously writes to (or triggers) all TAC5112 devices
  • Supports up to 32 configuration input/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 GPIOx, GPI1 or GPO1 pin can be configured as a secondary input/output data lane or as a secondary audio serial interface
  • The GPIOx, GPI1 or GPO1 pin can be used in a daisy-chain configuration of multiple TAC5112 devices
  • Supports one BCLK cycle data latching timing to relax the timing requirement for the high-speed interface
  • Programmable controller and target options for both primary and secondary audio serial interface
  • Ability to synchronize the multiple devices for the simultaneous sampling requirement across devices
  • Inter Channel Gain Alignment (ICGA) feature to align the DAC Channel gain across devices.
See the Multiple TAC5x1x Devices With a Shared TDM and I2C/SPI Bus application report for further details.
