Texas Instruments provides a recommended PCB layout in the CDCS503PW datasheet, but it's essential to follow good PCB design practices, such as using a solid ground plane, minimizing trace lengths, and keeping the device away from noise sources.
To ensure accurate clock output frequency, use a high-quality crystal oscillator, follow the recommended crystal load capacitance values, and ensure the PCB layout is optimized for minimal noise and signal integrity.
