CS4245-DQZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS4245-DQZ?
  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.
• How do I configure the CS4245-DQZ for master mode operation?
  To configure the CS4245-DQZ for master mode operation, set the M/S pin high and ensure that the BCK pin is driven by the CS4245-DQZ. Additionally, the LRCK pin should be driven by the CS4245-DQZ or an external clock source.
• What is the maximum clock frequency supported by the CS4245-DQZ?
  The CS4245-DQZ supports clock frequencies up to 50 MHz. However, the maximum clock frequency may vary depending on the specific application and system requirements.
• How do I handle the CS4245-DQZ's digital output data format?
  The CS4245-DQZ's digital output data format is 24-bit, MSB-first, and left-justified. The data is output on the DOUT pins, with the most significant bit (MSB) on DOUT23 and the least significant bit (LSB) on DOUT0.
• What is the purpose of the CS4245-DQZ's analog output stage?
  The CS4245-DQZ's analog output stage is used to drive external analog-to-digital converters (ADCs) or other analog circuitry. It provides a low-impedance output stage that can drive capacitive loads up to 100 pF.
