9ZX21501CKLFT

Overview

The Renesas 9ZX21501CKLFT is a low-power clock buffer and multiplexer designed for high-speed data transmission applications. It features a single differential input and fifteen differential HCSL outputs, providing a 1:15 fan-out ratio. The device supports maximum frequencies of 400 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. Packaged in a 64-VFQFPN (9x9 mm) surface-mount case with an exposed pad, it functions within an operating temperature range of 0°C to +70°C. This component integrates phase-locked loop capabilities to manage clock distribution efficiently.

Feature Summary

• 15-output differential HCSL clock buffer with 1:15 fan-out ratio
• Supports maximum operating frequency of 400 MHz
• Integrated PLL for clock signal management
• Differential input and output signaling

Applications

• Intel QuickPath Interconnect (QPI) systems
• PCI Express (PCIe) infrastructure
• High-performance server clock distribution

Procurement Notes

Verify the specific suffix 'CKLFT' against official Renesas documentation to confirm package type, tape-and-reel quantity, and RoHS compliance status. Ensure that the 64-VFQFPN footprint matches the target PCB layout requirements before procurement.

Selection Notes

Select this component when a 1:15 differential clock fan-out is required for PCIe or QPI architectures. Confirm that the system power supply remains within the 3.135 V to 3.465 V range and that the thermal environment stays between 0°C and +70°C.

Part Context

This part belongs to the 9ZX series of clock buffers and muxes from Renesas Electronics. It serves as a derivative solution for distributing reference clocks to multiple endpoints in high-speed serial link applications, ensuring signal integrity across the bus.

Replacement Considerations

Consult the official Renesas product selection guide for direct pin-compatible alternatives within the 9ZX family. Verify functional equivalence regarding frequency limits and output drive strength before substitution.
