CS4397-KSZ Frequently Asked Questions (FAQs)

  • The recommended power-up sequence is to apply VDD first, followed by VCC, and then the clock signal. This ensures proper initialization of the device.
  • To configure the CS4397-KSZ for master clock mode, set the MCLK pin as an output by writing to the Clock Control Register (CCR). Then, set the desired clock frequency using the Clock Frequency Register (CFR).
  • The Zero Flag (ZF) pin is an output that indicates when the digital signal processing (DSP) core is in a zero-flag state, which can be used to synchronize external processing or to detect errors in the audio data stream.
  • To implement a 24-bit audio interface, configure the CS4397-KSZ to use 24-bit data words by setting the Data Word Length (DWL) bits in the Audio Interface Control Register (AICR). Additionally, ensure that the external audio interface is configured to support 24-bit data transfer.
  • The maximum allowed clock jitter for the CS4397-KSZ is 500 ps peak-to-peak. Exceeding this limit may result in audio data corruption or errors.
