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 LMK04806BISQX/NOPB can be configured using the SPI interface. Texas Instruments provides a Clock Design Tool that can be used to generate the required configuration registers for a specific clock frequency. The tool can be downloaded from the Texas Instruments website.
The LMK04806BISQX/NOPB can generate clock frequencies up to 3072 MHz. However, the maximum frequency may be limited by the specific application and the quality of the external clock source.
Yes, the LMK04806BISQX/NOPB can be used in a system with multiple clock domains. It has multiple output clocks that can be configured to generate different frequencies, allowing it to support multiple clock domains.
To ensure low jitter, it's recommended to use a high-quality external clock source, such as a crystal oscillator or a low-jitter clock generator. Additionally, the LMK04806BISQX/NOPB has built-in jitter filtering and noise reduction features that can be enabled to minimize jitter.
