Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-frequency design practices, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines to ensure signal integrity.
The CDCM61001RHBR/2801 requires a 50-ohm output termination to ensure proper signal transmission. You can use a 50-ohm resistor in series with a capacitor to ground or a 50-ohm microstrip transmission line. The datasheet provides more information on output termination options.
The CDCM61001RHBR/2801 has an operating temperature range of -40°C to 85°C. However, it's essential to consider the junction temperature (TJ) when designing your system, as excessive temperatures can affect device performance and reliability.
To minimize jitter and ensure clock signal integrity, use a high-quality clock source, keep clock signal traces short and shielded, and use a low-jitter clock buffer or repeater if necessary. Additionally, follow good PCB design practices, such as using a solid ground plane and minimizing noise coupling.
Texas Instruments recommends using a decoupling capacitor (e.g., 0.1 μF) close to the device's power pins to filter out noise and ensure stable operation. You may also consider adding additional decoupling capacitors depending on your system's specific requirements.
