Additional Details

The ZL30108LDE1 requires a stable reference clock input. It typically operates from a 3.3V power supply. The device is usually supplied in a small surface-mount package. The output clock frequencies are programmable. Proper termination of the clock outputs is crucial for minimizing jitter. The DPLL parameters can be adjusted to optimize performance for different applications. Detailed specifications, including jitter performance and holdover accuracy, are available in the product datasheet.
