5P83904CMGK8 - Renesas Electronics

5P83904CMGK8 Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the 5P83904CMGK8?
  The recommended power-up sequence is to apply VDD first, followed by VDDA, and then the input clock signal. This ensures proper device initialization and prevents potential latch-up conditions.
• How do I configure the 5P83904CMGK8 for a specific output frequency?
  The output frequency can be configured by selecting the appropriate values for the SEL0-SEL2 pins, which control the internal PLL multiplier and divider ratios. Refer to the datasheet's frequency selection table and calculation formulas to determine the correct pin settings for your desired output frequency.
• What is the maximum input clock frequency supported by the 5P83904CMGK8?
  The maximum input clock frequency supported by the 5P83904CMGK8 is 350 MHz. Exceeding this frequency may result in device malfunction or reduced performance.
• Can I use the 5P83904CMGK8 in a system with multiple clock domains?
  Yes, the 5P83904CMGK8 can be used in systems with multiple clock domains. The device provides multiple output clocks with independent enable controls, allowing you to generate and manage multiple clock domains within a single device.
• How do I ensure the 5P83904CMGK8 is properly bypassed for low-power operation?
  To ensure proper bypassing for low-power operation, connect a 0.1 μF capacitor between the VDDA pin and the GND pin, and a 10 μF capacitor between the VDD pin and the GND pin. This helps to filter out noise and reduce power consumption during low-power modes.
