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.
