9DBU0241AKLFT

Overview

The 9DBU0241AKLFT is a clock buffer manufactured by Renesas Electronics Corporation, belonging to the 9DBU0241 family. It features four outputs and operates with a maximum output frequency of 100 MHz. The device accepts an input frequency up to 27 MHz and functions within a supply voltage range of 1.8 V. Key electrical parameters include a typical operating current of 15 mA and a jitter specification of 50 ps. The duty cycle maximum is rated at 55%. This component is designed for surface mount installation in a VFQFPN-32 package.

Feature Summary

• Four-output clock buffer architecture
• Maximum output frequency of 100 MHz
• Low power consumption with 15 mA operating current
• Jitter specification of 50 ps

Applications

• PCIe Gen1/Gen2/Gen3 clock distribution
• Zero-delay buffering applications
• System-on-Chip (SoC) timing solutions

Procurement Notes

Verify the suffix 'AKILFT' against official Renesas documentation to confirm specific packaging and tape-and-reel configurations. Ensure compliance with RoHS directives as indicated in manufacturer specifications. Confirm moisture sensitivity level (MSL) ratings prior to PCB assembly processes to prevent damage during reflow soldering.

Selection Notes

Select this component when a low-power, zero-delay buffer is required for PCIe interfaces. The 1.8 V supply voltage aligns with modern low-voltage logic standards. Verify that the 100 MHz maximum frequency meets system timing requirements. The VFQFPN-32 package offers a compact footprint suitable for space-constrained designs.

Part Context

The 9DBU0241AKLFT is part of Renesas' ultra-low-power PCIe clock buffer family. These devices are engineered for high-performance computing and communication systems requiring precise clock distribution with minimal power overhead. The series supports various PCIe generations through flexible output configurations.

Replacement Considerations

Consult Renesas or SiTime documentation for direct cross-reference models. Verify pin compatibility and electrical specifications before substituting with other clock buffers from different manufacturers.
