It takes one or two HCSL input pairs and fans out to four HCSL output pairs at up to 200 MHz — enough for PCIe Gen1 and Gen2 root complexes and slot clocks. Because it contains no PLL, there is no loop-filter noise, no lock-time delay, and the output-to-output skew is determined only by the internal buffer matching. This makes it a fit for systems that need deterministic latency and low additive jitter, such as server motherboards, storage backplanes, and base-station timing cards. ## Supply and temperature — design constraints at a glance The supply range is 3.14 V to 3.47 V. The operating temperature range is -40°C to 85°C. ## Lifecycle and compliance — active, ROHS3, no LTB notice The 9DML0451AKILFT carries an Active product status and is ROHS3 compliant.","metaTitle":"9DML0451AKILFT PCIe Clock Buffer, 200 MHz, HCSL, 24-QFN","metaDescription":"9DML0451AKILFT is a PLL-less 2:4 HCSL clock buffer for PCI Express, 200 MHz max, -40 to 85°C, 24-QFN.

If you need a PLL-based fanout with 400 MHz capability, the 9DB803DFLFT is a 1:8 HCSL buffer. Neither is a drop-in replacement — check the fanout ratio, supply tolerance, and temperature grade against your design."},{"question":"What is 9DML0451AKILFT's listed PLL status?","answer":"The 9DML0451AKILFT has no PLL. It is a straight HCSL buffer — no frequency multiplication or jitter attenuation. This means deterministic propagation delay but no cleanup of noisy input clocks."},{"question":"What is 9DML0451AKILFT's input and output type?","answer":"Both input and output are HCSL (High-Speed Current Steering Logic) differential pairs.
