9QXL2001CNHGI8

Overview

The 9QXL2001CNHGI8 is a single-circuit clock fanout buffer from the DB2000QL series, manufactured by Renesas Electronics Corporation. It features a 1:20 input-to-output ratio with differential HCSL signaling on both input and output sides. The device supports maximum frequencies up to 400 MHz and operates within a supply voltage range of 2.97V to 3.63V. Designed for surface mount installation, it is housed in an 80-GQFN (6x6) package with dual rows and an exposed pad. The component is rated for an ambient operating temperature range of -40°C to 105°C.

Feature Summary

• 1:20 differential fanout ratio with HCSL input and output signaling
• Supports frequencies up to 400 MHz
• Operating temperature range of -40°C to 105°C (TA)
• Integrated PLL functionality

Applications

• PCI Express (PCIe) clock distribution
• High-speed digital system timing
• Server and storage infrastructure clocking

Procurement Notes

Verify the specific ordering suffix NHGI8 against manufacturer documentation to confirm package type, tape-and-reel quantity, and moisture sensitivity level. Ensure the required supply voltage falls within the 2.97V to 3.63V range and that thermal management accommodates the 105°C maximum junction temperature rating for the intended application environment.

Selection Notes

Select this component when a single differential source must drive twenty differential loads using HCSL standards. Confirm compatibility with the target PCIe generation requirements and ensure the PCB layout supports the 80-GQFN footprint. Verify that the system power supply can maintain stability within the specified 2.97V to 3.63V window during peak current draw.

Part Context

This part belongs to the DB2000QL family of clock buffers designed for high-performance computing applications. It serves as a pin-compatible or functionally similar alternative to other members of the 9QXL2001 series, such as the 9QXL2001B, while offering specific electrical characteristics tailored for modern PCIe architectures requiring low jitter and wide temperature operation.

Replacement Considerations

Check datasheets for the 9QXL2001B and 9QXL2001A to verify pinout compatibility and electrical parameter overlaps. Ensure any substitute part matches the 80-GQFN package dimensions and maintains HCSL input/output compatibility.
