9QXL2001CNHGK

Overview

The Renesas 9QXL2001CNHGK is a single-circuit clock fanout buffer designed for high-speed digital interfaces. It features a 1:20 input-to-output ratio, supporting differential HCSL signaling on both input and output channels. The device operates at frequencies up to 400 MHz with a supply voltage range of 2.97V to 3.63V. It is housed in an 80-GQFN (6x6 mm) package with dual rows and an exposed pad, suitable for surface mount applications. The component supports an extended operating temperature range from -40°C to 105°C.

Feature Summary

• 1:20 differential fanout ratio with HCSL input and output signaling
• Maximum operating frequency of 400 MHz
• Supply voltage range of 2.97V to 3.63V
• Extended industrial temperature range (-40°C to 105°C)

Applications

• PCI Express (PCIe) clock distribution
• High-speed data communication systems
• Server and storage backplane clocking

Procurement Notes

Verify the specific ordering suffix CNHGK against the manufacturer's official datasheet to confirm pinout compatibility and packaging details. Ensure that the 80-GQFN thermal pad requirements are met during PCB layout. Confirm RoHS compliance status through the latest product release notes or distributor documentation before finalizing procurement.

Selection Notes

Select this component when a single differential source requires expansion into twenty differential loads. The HCSL interface ensures compatibility with standard PCIe and processor clock inputs. Consider the 80-VFQFN package size for board space constraints. Verify that the 400 MHz maximum frequency meets the system timing requirements and that the 2.97V–3.63V supply range aligns with the target power rail.

Part Context

This part belongs to the 9QXL2001 series of DB2000QL clock buffers. It serves as a fanout solution for distributing reference clocks in high-performance computing environments. The series typically includes variants with different temperature ratings and package options to suit various industrial and commercial design needs.

Replacement Considerations

Check for pin-compatible alternatives within the 9QXL2001 family. Verify if other suffixes offer different temperature ranges or packaging configurations while maintaining the same electrical specifications.
