A good PCB layout for the LMK04805BISQE/NOPB involves separating the analog and digital grounds, using a solid ground plane, and keeping the clock and data lines as short as possible. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To configure the LMK04805BISQE/NOPB for a specific clock frequency output, you need to set the appropriate values for the PLL loop filter components (R1, R2, C1, and C2) and the PLL multiplication factor (M) using the device's programming interface. You can use the TI Clock Design Tool or consult the device's datasheet for more information.
The LMK04805BISQE/NOPB can generate clock frequencies up to 3072 MHz, depending on the specific configuration and output divider settings.
To ensure that the LMK04805BISQE/NOPB is generating a low-jitter clock signal, you should use a high-quality crystal oscillator as the reference clock, keep the device's power supply noise to a minimum, and use a low-jitter PLL loop filter design. Additionally, you can use the device's built-in jitter cleaner feature to further reduce jitter.
Yes, the LMK04805BISQE/NOPB can be used in a redundant clocking system for high-reliability applications. The device's multiple clock outputs and built-in clock switching feature make it well-suited for redundant clocking systems.
