9QXL2000CNLGI

Clock Buffers, Drivers Overview

The 9QXL2000CNLGI is a high-performance clock buffer and distribution device manufactured by Renesas Electronics Corporation. It features a single differential HCSL input driving twenty differential HCSL outputs, providing a 1:20 fanout ratio. The device supports maximum operating frequencies up to 400 MHz and operates within a supply voltage range of 3.135V to 3.465V. Designed for surface-mount assembly, it is housed in a compact 72-VFQFPN package with dimensions of 10x10 mm. The component is qualified for industrial temperature ranges, functioning reliably between -40°C and +105°C ambient temperatures.

Clock Buffers, Drivers Feature Summary

• Provides 1:20 differential clock distribution from one HCSL input to twenty HCSL outputs
• Supports signal frequencies up to 400 MHz for high-speed data applications
• Operates on a 3.3V nominal supply (3.135V to 3.465V) with low power consumption characteristics
• Housed in a space-saving 72-lead VFQFPN package (10mm x 10mm) suitable for dense PCB layouts

Clock Buffers, Drivers Applications

• High-performance server and storage system clock distribution
• Networking equipment requiring multiple synchronized clock domains
• Industrial control systems demanding reliable timing signals across wide temperature ranges
• Data communication infrastructure utilizing PCIe or similar high-speed serial interfaces

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix CNLGI against official Renesas documentation to confirm package type, lead finish, and moisture sensitivity level. Ensure the procurement channel provides valid traceability for industrial-grade components. Confirm that the 72-VFQFPN package handling requirements align with standard surface-mount assembly processes.

Clock Buffers, Drivers Selection Notes

Select this component when a single reference clock must drive twenty downstream loads with minimal skew. The HCSL output signaling is compatible with standard PCIe and processor clock inputs. Verify that the 3.3V supply rail matches the target system design and that the 400 MHz frequency limit satisfies the highest clock requirement in the distribution tree.

Clock Buffers, Drivers Part Context

This part belongs to the Renesas clock buffer family, specifically designed for fanout applications. It serves as a critical timing element in complex digital systems where signal integrity and phase alignment are paramount. The 72-VFQFPN package allows for efficient board space utilization compared to larger legacy packages.

Clock Buffers, Drivers Replacement Considerations

Check for pin-compatible upgrades within the same Renesas series that may offer improved jitter performance or additional configuration options. Ensure any substitute maintains the 1:20 ratio and HCSL I/O standards to avoid schematic redesign.
