It contains no PLL — the outputs are a clean, low-jitter copy of the input, with no frequency multiplication or spread-spectrum synthesis. That makes it a fit for PCIe Gen1 and Gen2 root-complex-to-slot clock trees where the reference already meets the jitter spec and you just need to split the signal without adding phase noise. ## 200 MHz ceiling and the PCIe generation it serves Rated for a maximum output frequency of 200 MHz, this buffer covers the 100 MHz reference clock used by PCIe Gen1 and Gen2, plus any 125 MHz or 200 MHz non-PCIe differential clocks in the system. It does not support the 400 MHz references that Gen3 and Gen4 PLL-based buffers handle — if your design targets Gen3 or later, you need a part with a PLL, such as the 9DB803DFLFT (1:8, 400 MHz, PLL-based). ## Industrial temperature range — wider than the typical PCIe buffer Rated for -40°C to 85°C operating temperature, this part suits outdoor telecom cabinets, industrial backplanes, and engine-bay-adjacent electronics where the ambient can swing well beyond the 0°C to 70°C range of many PCIe clock buffers. The 9DBL411BGLFT, for example, is limited to 0°C to 70°C, so if your BOM calls for a wider temperature grade, the 9DML0441AKILFT is the drop-in candidate. ## Package and supply — standard PCIe footprint Housed in a 24-VFQFPN with exposed pad (4x4 mm), the part is surface-mount and requires the pad to be soldered to a ground plane for thermal and electrical integrity. Supply voltage is 3.3 V ±5% (3.135 V to 3.465 V), the standard PCIe clock buffer rail. The exposed pad must be connected to ground — a via array under the pad is recommended for heat spreading. ## Lifecycle and sourcing The 9DML0441AKILFT carries an Active lifecycle status with ROHS3 compliance. It is not nearing end-of-life, so it can be specified into new designs without an LTB risk.","metaTitle":"9DML0441AKILFT PCIe Clock Buffer, 200 MHz, 2:4 HCSL","metaDescription":"9DML0441AKILFT PCI Express clock buffer from Renesas. 200 MHz max, 2:4 HCSL fanout, no PLL.
