PCIe clock distribution with integrated PLL
No NRND or EOL notices are on record, so the part is safe to specify for new production builds and ongoing BOMs.
What the 1:9 fanout means for your BOM
Nine HCSL outputs from one input is the headline number for a system architect. If your design needs to clock eight PCIe slots plus one spare for a mezzanine connector, this part does it with a single device. The 9ZXL0851EKKLF sibling offers 1:8 fanout and adds Intel QPI support at 400 MHz, but for a pure PCIe clock tree the 9DBL0951BKILF's 1:9 ratio gives you one extra output without stepping to a larger package.
