9FGL0441BKILF PCI Express (PCIe) IC 100MHz 1 Output 32-VFQFPN (5x5)
The 9FGL0441BKILF is a Renesas (former IDT) 4‑output PCIe clock generator housed in compact 32‑VFQFPN surface‑mount package, generating 100MHz high‑quality differential HCSL clock signals compliant with PCIe Gen1‑Gen4 timing requirements. Powered by 3.3V supply, this PLL‑based timing IC supports common clock, SRnS and SRIS PCIe clock architectures, integrates spread‑spectrum clocking for EMI reduction, independent output enable control and one LVCMOS reference output for Wake‑on‑LAN function, delivering low‑jitter timing for high‑speed host adapter and embedded computing hardware.
Key features
● Four HCSL differential clock outputs with 100‑ohm default output impedance
● PCIe Gen1‑4 CC compliant, Gen2‑3 SRIS compatible
● Configurable spread‑spectrum clock with multiple modulation levels
● Dedicated OE# enable pin per clock output
● 3.3V LVCMOS REF output supporting Wake‑on‑LAN
● Ultra‑low phase jitter performance below 2ps RMS with SSC disabled
● SMBus interface for device configuration
● Industrial operating temperature range of ‑40°C to +85°C
FAQ
Q: What is the main supply voltage for 9FGL0441BKILF?
A: Nominal 3.3V supply voltage range from 3.135V to 3.465V.
Q: What function does the spread‑spectrum clock serve?
A: SSC reduces system electromagnetic interference by gentle frequency dithering without breaking PCIe compliance.
