Rated for a maximum frequency of 400 MHz, this buffer supports PCIe Gen1 (2.5 GT/s), Gen2 (5 GT/s), and Gen3 (8 GT/s) reference clock rates — the 400 MHz ceiling covers the 100 MHz nominal PCIe reference clock with margin for spread-spectrum modulation. ## Signal integrity and board integration Differential HCSL signaling on both input and output preserves signal integrity across the clock tree — the 1:8 fanout ratio means a single reference clock source drives up to eight PCIe endpoints without additional buffering stages, reducing jitter accumulation and BOM count. Housed in a 48-BSSOP package (0.295\" body width, 7.50 mm) with surface-mount termination, the part fits standard PCIe clock distribution layouts on multi-layer server, storage, and networking boards. ## Lifecycle and compliance status Fully ROHS3 compliant, meeting the latest EU restriction directive for lead-free manufacturing and reflow processes.","metaTitle":"Renesas 9DB803DFLFT PCIe Clock Buffer, 400MHz, 1:8, 48-SSOP","metaDescription":"Renesas 9DB803DFLFT PCIe clock buffer, 400MHz max, 1:8 fanout, HCSL I/O, 48-SSOP.
