9DBL0641BKILFT

Overview

The 9DBL0641BKILFT is a six-output zero-delay clock buffer from Renesas Electronics, designed for PCI Express applications. It accepts an HCSL differential input and provides LP-HCSL differential outputs with a nominal impedance of 100 ohms. The device operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 125 MHz. It is housed in a 40-pin VFQFPN package and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Six differential outputs configured as a zero-delay buffer
• HCSL input to LP-HCSL output translation
• 100-ohm differential output impedance
• Supports spread spectrum input signals

Applications

• PCI Express riser cards
• NVMe storage systems
• Networking accelerators
• Industrial control and embedded systems

Procurement Notes

Verify the specific suffix 'B' against official documentation, as public records primarily list the 'C' variant (9DBL0641CKILF) for this pin count and package. Confirm RoHS compliance status and moisture sensitivity level details directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when a six-channel distribution solution is required for PCIe Gen1 through Gen3 interfaces. Ensure the design accommodates the 40-pin VFQFPN footprint and that the power supply rails strictly adhere to the 3.135 V to 3.465 V specification for optimal performance.

Part Context

This part belongs to the 9DBL0641 series of low-power PCIe clock buffers. While the 'C' suffix version is widely documented in current catalogs, the 'B' suffix indicates a specific revision or manufacturing lot variation within the same functional family, sharing identical electrical characteristics and pinout definitions.

Replacement Considerations

The 9DBL0641CKILFT is a confirmed direct replacement offering identical functionality and packaging. Verify that any substitute maintains the 100-ohm output impedance and LP-HCSL signaling requirements.
