9DBL0442BKILFT

Overview

The 9DBL0442BKILFT is a clock buffer manufactured by Renesas Electronics, designed for PCIe applications. It features four outputs and operates at 3.3V with an integrated 100Ω termination impedance (ZO=100). The device supports low-power HCSL (LP-HCSL) signaling and functions within a frequency range of 1MHz to 200MHz in fan-out mode. It is housed in a compact surface-mount package suitable for space-constrained designs.

Feature Summary

• Four differential outputs with integrated 100Ω termination resistors
• Supports LP-HCSL output signaling for PCIe Gen1-Gen5 architectures
• Operates on a single 3.3V supply voltage
• Fan-out mode frequency range from 1MHz to 200MHz

Applications

• PCIe retimer and buffer circuits
• NVMe storage controllers
• Network infrastructure equipment
• Industrial control systems

Procurement Notes

Verify the specific suffix BKILFT against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity levels before assembly. Confirm lead availability and expected delivery times through authorized distributors as supply chain conditions may vary.

Selection Notes

Select this component when a 4-output clock distribution solution with integrated 100Ω termination is required for PCIe or similar high-speed serial interfaces. Compare jitter performance and power consumption against other members of the 9DBL0x family if different output counts or termination values (e.g., 85Ω) are needed.

Part Context

This part belongs to the Renesas 9DBL0x series of low-power, high-performance fan-out buffers. The series supports various PCIe clock architectures including Common Clock (CC) and Separate Reference (SRIS/SRNS). Other variants in the family offer different output counts (2, 6, or 8) and termination options to suit diverse system requirements.

Replacement Considerations

Direct replacements within the same family include the 9DBL0442CKILF, which shares similar electrical characteristics but may differ in packaging or suffix codes. Verify pinout compatibility and electrical parameters before substituting.
