CS5340-CZZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS5340-CZZR?
  The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures proper device operation and prevents latch-up.
• How do I optimize the analog-to-digital converter (ADC) performance for my specific application?
  To optimize ADC performance, ensure proper PCB layout, use a low-noise power supply, and optimize the analog input signal conditioning. Additionally, adjust the ADC clock frequency and sampling rate to suit your application's requirements.
• What is the maximum allowed input signal amplitude for the CS5340-CZZR?
  The maximum allowed input signal amplitude is 2.5Vpp differential, which is the maximum rating for the device. Exceeding this amplitude may result in distortion, clipping, or even device damage.
• How do I handle the digital output data from the CS5340-CZZR?
  The CS5340-CZZR outputs 24-bit data in a serial format. Ensure proper synchronization with the clock signal (SCLK) and frame signal (FSYNC) to correctly capture and process the output data.
• What is the purpose of the internal voltage reference (VREF) pin?
  The internal voltage reference (VREF) pin provides a stable voltage reference for the ADC. It can be used as a reference for external circuitry or as a voltage source for other components in the system.
