Product details

PLL-based zero-delay buffer for PCIe clock trees

The Renesas 9DB633AGLFT is a PLL-based zero-delay clock fanout buffer for PCI Express. It takes a single differential clock input and delivers six HCSL outputs, each running up to 110 MHz, with a 1:6 input-to-output ratio.

Supply and temperature — fit for controlled indoor environments

Operating from a 3.135 V to 3.465 V supply, the 9DB633AGLFT aligns with standard PCIe power rails. The commercial temperature grade (0°C to 70°C) limits deployment to controlled indoor equipment.

Package and footprint

Housed in a 28-TSSOP package (4.40 mm body width), the 9DB633AGLFT uses a standard surface-mount footprint common to many Renesas clock buffers.

Lifecycle and sourcing

The 9DB633AGLFT is listed as Active with ROHS3 compliance. There is no last-time-buy notice or obsolescence risk for new designs.

Frequently asked questions

Is 9DB633AGLFT obsolete?

No. The 9DB633AGLFT is listed as Active with no end-of-life notice. It is suitable for production BOMs and new designs.

What is the replacement for 9DB633AGLFT?

There is no direct replacement from Renesas listed as a successor. For a higher-frequency PLL-based HCSL fanout with 1:8 ratio and industrial temperature range, consider the 9ZXL0851EKKLF (400 MHz, -40°C to 85°C). For a non-PLL LP-HCSL fanout at 150 MHz, the 9DBL411BGLFT is an alternative but lacks the zero-delay PLL.

Can 9DB633AGLFT be used for PCIe Gen4?

The 9DB633AGLFT runs at 110 MHz max, which covers the 100 MHz PCIe reference clock frequency. However, PCIe Gen4 imposes tighter phase-jitter specifications (typically <0.5 ps RMS) that this part may not meet. Verify the jitter performance against your Gen4 controller requirements before specifying.
