PCIe clock generator — 1:5 fanout, 100 MHz
The 9FGV0441AKLF is a PLL-based clock generator from Renesas, built for PCI Express (PCIe) reference clock duty. It takes a single-ended crystal input and delivers up to five differential HCSL or LVCMOS outputs at 100 MHz, covering the standard PCIe Gen1–Gen3 reference clock rate.
Supply and temperature — 1.7–1.9 V, 0–70°C
Core supply runs from 1.7 V to 1.9 V, so it fits a 1.8 V rail with margin. Packaged in a 32-VFQFN with exposed pad (5×5 mm body), the thermal pad needs a solid via array to the ground plane to keep junction temperatures down under continuous 100 MHz operation.
Active status and compliance
Renesas lists the 9FGV0441AKLF as Active and ROHS3 compliant.
