Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good high-speed design practices, such as using a solid ground plane, minimizing trace lengths, and avoiding vias under the device.
The device has a thermal pad that must be connected to a solid ground plane to dissipate heat. Ensure good thermal conductivity by using a thermal interface material and a heat sink if necessary. Keep the device away from heat sources and ensure good airflow.
While the datasheet specifies a maximum operating frequency of 1.6 GHz, the actual frequency limit depends on the specific application, PCB layout, and signal integrity. It's recommended to perform signal integrity analysis and simulations to determine the maximum operating frequency for your specific design.
To minimize jitter and ensure signal integrity, use a well-designed PCB with controlled impedance, minimize trace lengths, and use signal termination resistors. Also, ensure that the power supply is clean and well-regulated, and consider using a clock jitter cleaner or a phase-locked loop (PLL) if necessary.
Texas Instruments recommends using a combination of ceramic and electrolytic capacitors for power supply decoupling. A 0.1 μF ceramic capacitor and a 10 μF electrolytic capacitor in parallel, placed close to the device, are a good starting point. However, the optimal decoupling capacitor values may vary depending on the specific application and PCB layout.
