It integrates a PLL (Phase-Locked Loop) to clean jitter and align the output phases to the input, accepting a single-ended or differential clock input and delivering four HCSL (High-Speed Current Steering Logic) outputs. The 1:4 fanout ratio makes it a natural fit for motherboards, add-in cards, and telecom line cards where a single clock source must drive multiple PCIe slots or endpoints. The part operates from a 3.135 V to 3.465 V supply and supports differential input and output. The maximum output frequency is 166 MHz, and the temperature range is -40°C to 85°C. ## Active lifecycle — no obsolescence pressure This is important for BOM planning: no urgent need to qualify a substitute or stockpile inventory. The part is also ROHS3 compliant, which covers the latest EU RoHS exemption categories. ## Package and mounting Housed in a 28-SSOP package (0.209\" body width, 5.30 mm), the 9DB433AFILF is a surface-mount device. The 28-SSOP footprint is common for clock buffers and fanout devices, so PCB layout reuse from similar parts is straightforward. The part ships in Tube, which is typical for low-volume production or prototyping; for higher-volume reflow, verify the tape-and-reel option if needed.","metaTitle":"9DB433AFILF PCIe Clock Fanout Buffer, 166 MHz, 28-SSOP","metaDescription":"9DB433AFILF is an active PCIe clock fanout buffer with integrated PLL, 1:4 HCSL outputs, 166 MHz max, -40 to 85°C, 28-SSOP.
