TLV320AIC3204IRHBT datasheet by Texas Instruments

TLV320AIC3204IRHBT Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TLV320AIC3204?
  The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
• How do I configure the TLV320AIC3204 for master or slave mode?
  The TLV320AIC3204 can be configured for master or slave mode by setting the M/S bit in the Control Register (CR) to 0 for master mode or 1 for slave mode.
• What is the maximum clock frequency supported by the TLV320AIC3204?
  The TLV320AIC3204 supports clock frequencies up to 50 MHz.
• How do I implement a microphone bias voltage on the TLV320AIC3204?
  The TLV320AIC3204 has a built-in microphone bias voltage generator that can be enabled by setting the MIC_BIAS_EN bit in the Control Register (CR). The bias voltage can be set to 1.5V, 2.0V, or 2.5V using the MIC_BIAS_SEL bits.
• What is the purpose of the PLL clock domain on the TLV320AIC3204?
  The PLL clock domain is used to generate a clock signal for the audio interface. It can be used to generate a clock signal for the I2S, SPI, or AC'97 interfaces.
