Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using 50-ohm transmission lines for clock signals.
The LMK61I2-100M00SIAT requires a stable power supply with minimal noise and ripple. Use a low-ESR capacitor (e.g., 100nF) close to the power pins, and consider adding a 10uF bulk capacitor for further decoupling. Ensure the power supply can provide the required current (typically 50mA).
The LMK61I2-100M00SIAT is specified to operate up to 100MHz, but the actual maximum frequency may be limited by the specific application, PCB layout, and clock signal quality. In general, it's recommended to derate the clock frequency by 10-20% to ensure reliable operation.
The LMK61I2-100M00SIAT has a programmable clock output frequency. Use the TI Clock Design Tool or consult the datasheet to determine the required register settings for the desired output frequency. Ensure the input clock frequency and output frequency are within the specified ranges.
The LMK61I2-100M00SIAT has a typical jitter performance of <1ps RMS (random jitter) and <10ps peak-to-peak (periodic jitter) for a 100MHz output clock. However, actual jitter performance may vary depending on the specific application, PCB layout, and clock signal quality.
