Product details

1:4 HCSL fanout with integrated PLL for Ethernet and PCIe

The Renesas 9DBV0441AKILF is a PLL-based clock buffer that takes one HCSL input and delivers four HCSL outputs, purpose-built for Ethernet and PCI Express (PCIe) reference-clock distribution. The integrated PLL cleans up incoming jitter within its loop bandwidth, which matters when a noisy board-level clock source feeds a switch PHY or a PCIe root complex. The 1:4 fanout ratio is sized for a small clock tree. The differential HCSL I/O preserves signal integrity over short board traces.

Renesas lists the 9DBV0441AKILF as Active. ROHS3 compliance is confirmed.

Frequently asked questions

Is 9DBV0441AKILF RoHS compliant?

Yes, it is ROHS3 Compliant.

Can 9DBV0441AKILF be used with a 3.3V supply?

No. The supply range is 1.7V to 1.9V. A 3.3V rail will damage the device. A local 1.8V regulator is required.

What are alternatives to 9DBV0441AKILF?

For a higher fanout or higher frequency, the 9ZXL0851EKKLF (1:8, 400 MHz) and 9ZXL1231EKILF (1:12, 400 MHz) are in the same Renesas family but target Intel QPI and PCIe at 400 MHz. The 9DB803DFLFT is a 1:8 PCIe-only buffer but operates from 3.3V and only over the commercial temperature range (0°C to 70°C). Choose the 9DBV0441AKILF when you need a 1:4 fanout at 137.5 MHz max with industrial temperature range and a 1.8V supply.
