ZL4026x PCIe® Clock Trees

ZL4026x PCIe® Clock Trees

Microchip's ZL4026x family is made up of high-performance, ultra-low jitter, and low-power PCIe® Gen 1 to 5, Intel QPI fan-out buffers with individual output enable pins. Using the 2-output ZL40262 or the 4-output ZL40264 and utilizing the individual output pin, users can create hot-swappable PCIe clock trees. The rich feature-set of the ZL4026x devices make them suitable for a range of applications including PCI Express generation 1/2/3/4/5 clock distribution, Intel QPI and UPI distribution, servers, storage and data centers, switches, and test equipment.

Features
  • One differential input which accepts any differential format
