Microchip Technology, Inc. Low Skew, Low Jitter, 8 O/P HCSL Buffer ZL40268

The ZL40268 is 3x8 HCSL/LVDS/LVPECL clock fan out buffer with ultra-low additive jitter of 24fs capable of operating at frequencies up to 1.5 GHz. Using the 8 output ZL40268 and utilizing the individual output pins or I2C interface, you can create hot-swappable PCIe clocktrees. Applications include PCI Express generation 1/2/3/4/5 clock distribution, Intel QPI and UPI distribution, Servers, storage and data centers, switches and routers.
