9ZX21201AKLFT

Overview

The Renesas Electronics 9ZX21201AKLFT is a high-performance zero-delay buffer (Z-BUFFER) designed for Intel QPI and PCI Express applications. It features one differential HCSL input driving twelve differential outputs with a 1:12 ratio. The device operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 150MHz. Packaged in a 64-VFQFPN (9x9mm) exposed pad surface-mount case, it functions across an operating temperature range of 0°C to +70°C.

Feature Summary

• Zero-delay buffering architecture ensuring minimal phase offset between input and output clocks.
• Converts single-ended or differential inputs to twelve differential HCSL outputs.
• Integrated PLL functionality for jitter cleaning and clock generation.
• Optimized for Intel QPI and PCIe system architectures.

Applications

• Intel QuickPath Interconnect (QPI) clock distribution
• PCI Express (PCIe) compliant clocking systems
• High-performance server and computing platforms

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status through official datasheets prior to integration. Ensure ESD handling protocols are followed during assembly due to the fine-pitch VFQFPN package requirements.

Selection Notes

Select this component when a 1:12 fanout with zero-delay characteristics is required for HCSL signaling. The 64-VFQFPN package suits designs needing a compact footprint. Verify that the system power supply remains strictly within the 3.135V to 3.465V range to ensure proper operation and signal integrity.

Part Context

This part belongs to the Renesas 9ZX series of high-performance clock buffers. It serves as a critical timing element in complex digital systems requiring precise clock synchronization. The device replaces older discrete buffer solutions by integrating multiple outputs and PLL capabilities into a single integrated circuit.

Replacement Considerations

Consult the manufacturer's cross-reference guide for pin-compatible alternatives. Verify that any substitute maintains the same 64-VFQFPN package dimensions and electrical specifications for HCSL outputs.
