Product details

PCIe clock generator for the 1.8V plane

The 9FGV0241AKLF is a single-circuit PLL clock generator from Renesas, purpose-built for PCI Express (PCIe) reference clocking. It accepts a crystal input and delivers one HCSL and up to three LVCMOS outputs at frequencies up to 100 MHz, with a 1:3 input-to-output ratio. The differential outputs are HCSL; the single-ended outputs are LVCMOS. The supply range is 1.7V to 1.9V — it runs off the 1.8V rail. The 24-VFQFN exposed-pad package (4x4 mm) keeps the footprint small. Operating temperature is 0°C to 70°C.

What the 100 MHz ceiling means for PCIe generation

The maximum output frequency is 100 MHz, which aligns with PCIe Gen1 through Gen3 reference clock requirements. The integrated PLL cleans up the crystal input jitter, so you can use a standard crystal rather than a costly TCXO. The 1:3 fanout replaces a separate clock buffer in low-port-count designs.

Frequently asked questions

Does 9FGV0241AKLF support PCIe Gen4?

No — the maximum output frequency is 100 MHz, which covers PCIe Gen1 through Gen3 reference clock requirements. Gen4 and Gen5 need higher-frequency spread-spectrum clocks (typically 400 MHz or above) that this part cannot generate.

Is 9FGV0241AKLF a direct replacement for 9FGV0241AKLFT?

Electrically identical — the only difference is the packaging medium. 9FGV0241AKLF ships in tube; 9FGV0241AKLFT ships in Tape & Reel. Same silicon, same specs, same footprint.
