Description

[CREATE AND SAMPLE YOUR CUSTOM ZL40250 HERE](https://clockworks.microchip.com/microchip/design/inputZL) The ZL40250 is a 6-output programmable fanout buffer with multi-format I/O and dividers offers the ability to create multiple copies of a clock signal and distribute them among several loads with minimal additive jitter. The ZL40250 features an intuitive graphical user interface (GUI) and the ability to create factory pre-programmed devices with ease using Microsemi’s web tool, miClockDesigner. These pre-programmed devices—which have pin-selectable configurations at power-up—ensure clock availability and proper system bring-up for all applications.
