CS8415A-CZZR datasheet by Cirrus Logic

CS8415A-CZZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS8415A-CZZR?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I configure the CS8415A-CZZR for master clock mode?
  To configure the CS8415A-CZZR for master clock mode, set the MCKE pin high and the MCKI pin low. This enables the internal clock generator, and the device will output a clock signal on the MCKO pin.
• What is the maximum clock frequency supported by the CS8415A-CZZR?
  The CS8415A-CZZR supports clock frequencies up to 256 fs (fs = 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or 192 kHz). However, the actual maximum frequency may be limited by the specific application and system requirements.
• How do I handle the CS8415A-CZZR's digital output data format?
  The CS8415A-CZZR's digital output data format is 24-bit, 2's complement, MSB-first. The device outputs data in a serial format, with the left and right channels multiplexed on the same output pin.
• What is the purpose of the CS8415A-CZZR's analog output stage?
  The CS8415A-CZZR's analog output stage is a differential output stage that provides a low-impedance, high-current drive capability for the analog output signals. This stage is designed to drive external analog-to-digital converters (ADCs) or other devices.
