Texas Instruments provides a recommended PCB layout in the CDCR61APW datasheet, but it's essential to follow good PCB design practices, such as using a solid ground plane, separating analog and digital signals, and minimizing loop areas. Additionally, use a 4-layer PCB with a dedicated power plane and a dedicated ground plane to reduce noise and EMI.
The CDCR61APW is a highly configurable device. To configure it for a specific clock frequency, you need to set the appropriate values for the R, N, and M dividers using the device's control registers. You can use the TI Clocking Architect (TCA) software tool to generate the required configuration settings for your specific clock frequency.
The CDCR61APW can handle input clock frequencies up to 2.5 GHz. However, the maximum input frequency may vary depending on the specific application and the quality of the input clock signal. It's essential to ensure that the input clock signal meets the device's input requirements and to follow proper PCB design practices to minimize signal degradation.
Proper power supply and decoupling are crucial for the CDCR61APW's operation. Ensure that the device is powered from a clean, low-noise power supply, and use a sufficient number of decoupling capacitors (at least 4-6) with a total capacitance of around 10-20 μF. Place the decoupling capacitors close to the device's power pins and use a low-ESR capacitor for the main decoupling capacitor.
The typical power consumption of the CDCR61APW varies depending on the specific configuration, clock frequency, and output load. However, according to the datasheet, the typical power consumption is around 350-400 mW at a 1.8-V supply voltage and a 100-MHz clock frequency. You can use the TI Power Estimator (TPE) software tool to estimate the power consumption for your specific application.
