Product details

PCIe clock distribution without the PLL

The Renesas 9DML0451AKILF is a 2:4 HCSL fanout buffer for PCI Express (PCIe) clock distribution. The PLL entry reads No, so this part is a pure fanout buffer that distributes an incoming HCSL reference clock to up to four output paths.

Supply rail and temperature grade

Supply voltage range is 3.14 V to 3.47 V. The -40°C to 85°C operating temperature covers industrial environments.

Sourcing and lifecycle

Lifecycle status is Active per the manufacturer — no NRND or EOL notice. For BOM planning, there is no last-time-buy window to track.

Frequently asked questions

Is 9DML0451AKILF a PLL or fanout buffer?

It is a fanout buffer — the PLL entry is No. This part distributes an incoming HCSL clock without frequency multiplication or jitter attenuation. For PLL-based clock generation, consider the 9ZXL0851EKKLF or 9ZXL1231EKILF.

How does 9DML0451AKILF compare to other PCIe clock buffers?

The key difference versus PLL-based buffers like 9ZXL0851EKKLF (1:8, 400 MHz) and 9ZXL1231EKILF (1:12, 400 MHz) is that 9DML0451AKILF is a pure fanout — no PLL, lower additive jitter, simpler loop filter. Versus the commercial-grade 9DBL411BGLFT (1:4, 150 MHz, 0°C to 70°C), this part offers a wider industrial temperature range and higher 200 MHz ceiling.

What is the input and output signal format of 9DML0451AKILF?

Both input and output are HCSL (High-Speed Current Steering Logic), differential throughout. The part accepts a differential HCSL input and outputs four differential HCSL copies.
