9ZX21207BKLF

Overview

The 9ZX21207BKLF is a high-performance zero-delay buffer manufactured by Renesas Electronics Corporation, designed for demanding clock distribution applications. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum input frequency of 150MHz. The device features a single circuit configuration with twelve outputs, providing a 1:12 fan-out ratio. It utilizes HCSL input signaling and delivers LP-HCSL output signals, ensuring signal integrity across the network. The component is rated for an operating temperature range of 0°C to +70°C and is housed in a 56-lead VFQFPN package with exposed pad for efficient thermal management.

Feature Summary

• Provides high-performance clock buffering with low propagation delay characteristics suitable for precision timing requirements.
• Supports differential HCSL input and LP-HCSL output signaling formats for robust noise immunity.
• Features a compact surface-mount package design optimized for high-density board layouts.

Applications

• Clock distribution networks in high-speed computing systems
• PCI Express (PCIe) infrastructure timing solutions
• Intel QuickPath Interconnect (QPI) clock generation

Procurement Notes

Verify the specific suffix 'BKLF' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the procurement source provides valid RoHS compliance documentation and moisture sensitivity level (MSL) ratings prior to purchase. Cross-reference the part number with official Renesas databases to confirm availability status and any recent product change notices affecting the component.

Selection Notes

Select this component when a single differential input must be distributed to multiple loads requiring LP-HCSL signaling. Consider the 12-output capacity and 150MHz frequency limit relative to system bandwidth needs. Evaluate the VFQFPN package dimensions against available PCB real estate. Confirm that the power supply voltage aligns with the specified 3.135V to 3.465V range for optimal performance.

Part Context

This part belongs to the 9ZX series of clock buffers from Renesas, which are engineered for high-frequency digital applications. The series typically includes variants with different output counts and packaging options. The 9ZX21207 specifically addresses scenarios requiring moderate fan-out capabilities with strict timing constraints, fitting into the broader portfolio of timing and synchronization integrated circuits.

Replacement Considerations

Consult official Renesas cross-reference tools for direct replacements. Verify that any substitute maintains identical HCSL/LP-HCSL interface compatibility and package footprint. Ensure the alternative component meets or exceeds the 150MHz frequency specification and 12-output requirement without altering system timing margins.
