CS5364-CQZR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS5364-CQZR?
  The recommended power-up sequence is to apply VDD (analog power) first, followed by VCC (digital power), and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the analog input impedance for the CS5364-CQZR?
  To optimize the analog input impedance, use a series resistor (Rs) and a capacitor (Cs) in parallel to create a low-pass filter. The values of Rs and Cs depend on the specific application and input signal characteristics.
• What is the maximum clock frequency supported by the CS5364-CQZR?
  The CS5364-CQZR supports clock frequencies up to 100 MHz. However, the actual clock frequency used may be limited by the specific application and system requirements.
• How do I handle clock jitter and skew in the CS5364-CQZR?
  To minimize clock jitter and skew, use a high-quality clock source and ensure that the clock signal is properly terminated and routed. Additionally, use a clock buffer or repeater if necessary to maintain signal integrity.
• What is the recommended layout and routing for the CS5364-CQZR?
  To minimize noise and interference, use a multi-layer PCB with separate analog and digital ground planes. Keep analog and digital signals separate, and use shielding and guard rings around sensitive signals.
