The ZL40250LDG1 is a high-performance clock buffer, driver and regenerator distinctively suitable for any application which requires high-speed clock or signal distribution. It is an ideal solution for precision timing and skew control applications. Clock drivers are amongst the most vital fundamental functions in any digital system, and this device is particularly suitable for addressing those challenges.

Application Field

The ZL40250LDG1 is well suited for various clock distribution applications such as high-speed clocks, data transfer between chips, and distributing clocks through multiple trace interconnects. The device is both suitable for use in larger configurations with as many as 24 outputs and also for single applications with just one output.It can be used in applications such as Gigabit Ethernet, Fibre Channel, Serial ATA, and PCI Express, as well as in many other applications requiring jitter-free clock distribution. This device is suitable for reducing the propagation delay in large digital systems, specifically in high-speed processors, communication interface devices and wide-bus systems.

Working Principle

The ZL40250LDG1 operates by buffering an externally generated clock signal that has already been stripped of any interference, and then regenerating a cleaner clock signal (output) with improved characteristics. The device is capable of driving one or two trace interconnects with a single output buffered clock signal. That output buffered clock signar can then be degraded in order to later feed multiple tracing interconnects simultaneously. To guarantee noise performance, the ZL40250LDG1 follows a standard I/O interface and has advanced power management circuitry. This device comes with integrated power-on reset (POR) and a fast start-up time. This device is suitable for providing low-skew fan-out of a clock signal while reducing the load and power consumption along the clock path, and is especially designed to reduce jitter up to the 1.5 mV, allowing it to achieve excellent accuracy in most clock distribution applications.

Conclusion

The ZL40250LDG1 is a highly effective clock buffer, driver and regenerator suitable for a wide range of applications requiring high-speed clock or signal distribution. It reduces the propagation delay in large digital systems, providing low-skew fan-out of a clock signal while significantly reducing the load along the clock path and power consumption. The device is well suited for applications such as Gigabit Ethernet, Fibre Channel, Serial ATA, and PCI Express, and is recognized for its excellent accuracy in most clock distribution applications.
