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. Rated for the industrial temperature range (-40°C to 85°C), it fits outdoor telecom cabinets and factory-floor controllers where the ambient can swing well past commercial limits. The 1:4 fanout ratio is sized for a small clock tree. The differential HCSL I/O preserves signal integrity over short board traces. ## Lifecycle and sourcing posture Renesas lists the 9DBV0441AKILF as Active. ROHS3 compliance is confirmed.","metaTitle":"Renesas 9DBV0441AKILF PLL Clock Buffer, 137.5MHz, HCSL","metaDescription":"Renesas 9DBV0441AKILF PLL clock buffer: 1:4 HCSL fanout, 137.5MHz max, 1.7-1.9V supply, -40 to 85°C, 32-VFQFPN.
