It integrates a PLL, accepts an HCSL input and delivers HCSL outputs. Maximum output frequency is 400 MHz. The 1:8 fanout ratio distributes a clean reference clock to eight PCIe slots, endpoints, or switch ports. ## Supply and temperature — indoor equipment only Supply voltage range is 3.135 V to 3.465 V. Operating temperature is 0°C to 70°C, limiting this part to commercial/indoor environments. Not rated for industrial or automotive under-hood use. If your application needs -40°C to 85°C, the 9ZXL0851EKKLF covers that range with the same 1:8 HCSL fanout and PLL. ## Package and mounting — 48-lead SSOP, 7.5 mm wide Housed in a 48-lead BSSOP (SSOP) package with 0.295 inch (7.50 mm) body width. Surface-mount only. The supplier device package is 48-SSOP. This is a standard footprint for PCIe clock buffers; verify the land pattern against your PCB layout before committing the BOM. ## Lifecycle and sourcing — active, no LTB risk Renesas lists the 9DB803DFLF as Active with ROHS3 compliance. No end-of-life notice, no last-time-buy window. If you are stocking spares for a long-life system, the active status means you can plan replenishment without an EOL scramble.","metaTitle":"Renesas 9DB803DFLF PCIe Clock Buffer, 400 MHz, 1:8 HCSL","metaDescription":"Renesas 9DB803DFLF PCIe clock buffer with integrated PLL, 1:8 HCSL fanout, 400 MHz max, 48-SSOP.
