9QXL2001CNHGK8

Overview

The 9QXL2001CNHGK8 is a single-circuit clock fan-out 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 channels. The device supports maximum frequencies up to 400 MHz and operates within a supply voltage range of 2.97V to 3.63V. Designed for PCI Express applications, it functions reliably across an operating temperature range of -40°C to 105°C (TA). The component is housed in an 80-GQFN package measuring 6x6 mm, utilizing surface mount technology.

Feature Summary

• 1:20 differential fan-out ratio with HCSL input and output signaling
• Maximum operating frequency of 400 MHz
• Integrated PLL for clock generation and distribution
• Wide supply voltage range of 2.97V to 3.63V

Applications

• PCI Express (PCIe) clock distribution networks
• High-speed data communication systems
• Server and storage infrastructure timing

Procurement Notes

Verify the specific ordering suffix CNHGK8 against official Renesas documentation to confirm package type, tape-and-reel quantity, and environmental compliance status. Ensure compatibility with existing PCB footprints for the 80-GQFN (6x6) package before procurement.

Selection Notes

Select this component when a single differential input requires expansion into twenty differential outputs at frequencies up to 400 MHz. Confirm that the system power supply remains within the 2.97V to 3.63V range and that the thermal environment supports operation up to 105°C ambient temperature.

Part Context

This part belongs to the DB2000QL family of high-performance clock buffers. It serves as a signal integrity solution for distributing reference clocks in complex digital systems requiring multiple synchronized outputs from a single source.

Replacement Considerations

Check for direct pin-compatible alternatives within the 9QXL2001 series or other Renesas fan-out buffers with matching 1:20 ratios and HCSL interfaces. Verify electrical parameters such as jitter performance and supply voltage tolerance match the original design requirements.
