The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents latch-up.
When using CDC2351DBR in a PLL configuration, it's essential to ensure the clock signal is clean and stable. Use a clock buffer or a dedicated clock generator to provide a low-jitter clock signal, and consider adding a clock filter to remove any noise or glitches.
The maximum frequency limit for CDC2351DBR is 200 MHz. However, the actual frequency limit may vary depending on the specific application, board layout, and environmental conditions. It's recommended to consult the datasheet and perform thorough testing to determine the maximum frequency limit for your specific use case.
To optimize CDC2351DBR for low power consumption, use the lowest possible voltage supply (1.8V or 2.5V), reduce the clock frequency, and minimize the output load capacitance. Additionally, consider using the device's built-in power-down mode or shutdown feature to reduce power consumption when not in use.
CDC2351DBR has a maximum junction temperature of 150°C. Ensure proper thermal management by providing adequate heat sinking, using a thermal pad or heat spreader, and keeping the device away from heat sources. Monitor the device's temperature and adjust the operating conditions accordingly to prevent overheating.
