9DBL0741BKILFT

Overview

The 9DBL0741BKILFT is a zero-delay fanout buffer manufactured by Renesas Electronics Corporation, designed for PCI Express (PCIe) clock distribution. It features a single HCSL differential input and eight LP-HCSL differential outputs, providing a 1:8 ratio. The device operates at frequencies up to 200 MHz with a supply voltage range of 3.135 V to 3.465 V. Packaged in a 48-VFQFPN (6x6 mm) surface-mount format, it supports an operating temperature range of -40°C to +85°C. This component integrates phase-locked loop (PLL) capabilities to minimize jitter while maintaining signal integrity across high-speed digital interfaces.

Feature Summary

• Provides 1:8 differential clock fanout from one HCSL input to eight LP-HCSL outputs
• Supports maximum operating frequency of 200 MHz for PCIe applications
• Integrates PLL circuitry for zero-delay buffering and jitter reduction
• Operates on a single 3.3 V nominal supply voltage (3.135 V to 3.465 V)

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed server and storage system backplanes
• Network infrastructure equipment requiring low-jitter clocking

Procurement Notes

Verify component status as the 9DBL0741 series may be subject to discontinuation notices. Confirm availability through authorized distributors or check for active replacement part numbers such as those in the 9DBL0841 family if pin-compatible alternatives are required. Ensure RoHS3 compliance matches specific project requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring eight differential clock outputs driven by a single source with minimal skew. Verify that the PCB layout supports the 48-VFQFPN package dimensions. Ensure the power supply rails remain within the specified 3.135 V to 3.465 V range to maintain timing accuracy and output amplitude specifications defined in the datasheet.

Part Context

This part belongs to the Renesas 9DBL series of PCIe clock buffers and generators. These devices are engineered to meet the stringent jitter and skew requirements of modern high-speed serial interfaces. The 9DBL0741 variant specifically addresses designs needing eight output channels, distinguishing it from lower-channel variants like the 9DBL0441 or higher-channel options within the same product family.

Replacement Considerations

Check for official replacement part numbers provided by Renesas Electronics, such as the 9DBL0841 series, which may offer similar functionality or enhanced features. Verify pin compatibility and electrical specifications before substituting to ensure seamless integration into existing hardware designs without requiring schematic modifications.
