The 400 MHz maximum frequency covers PCIe Gen1 through Gen3 reference clock requirements. The 1:6 input-to-output ratio means one reference clock source feeds up to six PCIe slots, QPI links, or PCH interfaces.
No last-time-buy notice, no end-of-life window to track. The -40°C to 85°C rating also means it qualifies for environments where the commercial-grade 9DB803DFLFT (0°C to 70°C) would not be acceptable.
The suffix 'T' typically denotes tape-and-reel packaging. The 'LF' suffix indicates lead-free / RoHS-compliant finish. The EKILF variant ships in a tray; the EKILFT would be on tape and reel. Electrical specifications are identical.
The 9DB803DFLFT is a PCIe clock buffer with 1:8 fanout and commercial temperature range (0°C to 70°C). The 9ZXL0652EKILF has a 1:6 fanout and industrial temperature range (-40°C to 85°C). They are not pin-compatible direct replacements. Check the fanout count and temperature requirements before substituting.
PCIe Gen4 typically requires a 100 MHz reference clock with tighter jitter specifications. Verify the jitter performance against your Gen4 controller's requirements before committing this part to a Gen4 design.
