PCIe clock distribution with 1:4 HCSL fanout
The 9DB433AGILFT is a zero-delay PCI Express clock fanout and buffer that takes a single-ended or differential clock input and distributes it across four HCSL (High-Speed Current Steering Logic) outputs at up to 166 MHz. This is the standard output format for PCIe reference clocks — the differential swing and common-mode voltage are specified to mate directly with the PCIe root complex or switch without external level translation.
Second-source and peer comparison
The closest functional peer is the 9ZXL0851EKKLF, which also outputs HCSL and targets PCI Express, but offers a 1:8 fanout ratio and supports Intel QPI in addition to PCIe. The 5V41066PGGI8 provides HCSL and LVDS outputs but has a non-differential input, so it cannot accept a differential clock source.
Sourcing and procurement
The Tape & Reel packaging is suitable for automated pick-and-place assembly.
