9DB833AFLFT

Overview

The 9DB833AFLFT is a clock buffer manufactured by Renesas Electronics, designed for PCI Express Gen 3 applications. It features eight outputs and supports a maximum input frequency of 166 MHz. The device operates within a supply voltage range of 3.135 V to 3.465 V and utilizes an SSOP-48 package. It exhibits a maximum propagation delay of 0 ps and functions within a temperature range of 0°C to +70°C. This component serves as a zero-delay buffer for distributing clock signals in high-speed digital systems.

Feature Summary

• Eight-output configuration optimized for PCIe Gen 3 clock distribution
• Zero propagation delay (max 0 ps) for precise timing alignment
• Supports input frequencies up to 166 MHz with HCSL I/O standards
• Operates on a single 3.3V supply (3.135V–3.465V)

Applications

• PCI Express Gen 3 system clock distribution
• High-performance server and storage backplanes
• Network infrastructure equipment requiring low-jitter clocking

Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be discontinued or subject to end-of-life notifications. Confirm that the SSOP-48 package and 0°C to +70°C industrial temperature range meet the design requirements. Ensure compatibility with existing PCB footprints and verify RoHS compliance documentation matches the manufacturing batch.

Selection Notes

Select this component when an eight-channel clock buffer is required for PCIe Gen 3 interfaces. Compare against the 9DB833AGILF if a TSSOP-48 package or extended temperature range (-40°C to +85°C) is necessary instead of the SSOP-48 form factor. Ensure the design accommodates the 166 MHz maximum input frequency constraint.

Part Context

This part belongs to the 9DB833 series of clock buffers from Renesas. It is functionally related to other variants such as the 9DB833AFLFT (discontinued) and the 9DB833AGILF. The suffix 'FLFT' indicates the specific package type (SSOP-48), lead-free composition, and tape-and-reel packaging format.

Replacement Considerations

The 9DB833AGILFT is listed as a similar replacement option. Verify pinout compatibility and electrical specifications before substitution.
