It targets Intel QPI and PCI Express (PCIe) clock trees where low additive jitter and matched skew across the four lanes are required. The 150 MHz maximum frequency and 1:4 fanout ratio mean this part fits a PCIe Gen1/Gen2 reference-clock distribution scheme where one source fans out to four endpoints — a PCH, a CPU, and two downstream devices, for example. ## Package and board integration The 0.50 mm pitch QFN pads demand a solder-paste stencil aperture sized per the land pattern in the Renesas application note for this package family. Commercial temperature grade (0°C to 70°C) limits the part to indoor equipment — no cold-start at -40°C.","metaTitle":"Renesas 9DBL411BKLFT Fanout Buffer, 150 MHz, 1:4, LP-HCSL","metaDescription":"Active Renesas 9DBL411BKLFT differential fanout buffer. 1:4 ratio, 150 MHz max, LP-HCSL output, 20-VFQFN.
