A good PCB layout for the CDCE18005RGZT involves keeping the input and output traces short and separate, using a solid ground plane, and placing decoupling capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To choose the correct output frequency, consider the specific requirements of your application, such as the clock frequency required by your processor or other components. The CDCE18005RGZT can generate frequencies from 10 kHz to 230 MHz, so select a frequency that meets your application's needs.
The CDCE18005RGZT can handle input frequencies up to 230 MHz. However, it's recommended to use an input frequency between 10 MHz and 50 MHz for optimal performance.
To configure the CDCE18005RGZT for a specific output frequency, use the device's internal PLL and dividers to generate the desired frequency. The device has a programmable PLL that can be configured using the S0, S1, and S2 pins. Consult the datasheet for specific configuration details.
The power consumption of the CDCE18005RGZT depends on the output frequency and load. To minimize power consumption, use the lowest possible output frequency, minimize the load capacitance, and use a low-power mode if possible. The device has a power-down mode that can be used to reduce power consumption when the device is not in use.
