9ZML1232BKLF

Overview

The 9ZML1232BKLF is a low-power clock buffer and multiplexer manufactured by Renesas Electronics. It features two differential inputs and twelve LP-HCSL outputs, packaged in a 72-VFQFPN exposed pad. The device supports input frequencies up to 150 MHz and operates within a supply voltage range of 3.135 V to 3.465 V. It functions as a DB1200ZL derivative for server applications, offering selectable SMBus addresses and separate VDDIO for output power management.

Feature Summary

• Supports 2:12 differential multiplexing with LP-HCSL output types
• Includes nine selectable SMBus addresses for multi-device configurations
• Features separate VDDIO supply for flexible output voltage levels
• Complies with DB1200ZL performance specifications for server environments

Applications

• Server clock distribution networks
• DB1200ZL compatible system designs
• High-speed data center infrastructure

Procurement Notes

Verify the specific suffix 'BKLF' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 72-VFQFPN form factor. Confirm that the operating temperature range meets system requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate that the moisture sensitivity level aligns with assembly process capabilities.

Selection Notes

Select this component when a DB1200ZL equivalent is required for server clock distribution. Choose this part for designs needing dual-input multiplexing with twelve low-power HCSL outputs. Consider this IC for systems requiring configurable SMBus addressing to manage multiple clock buffers on a single bus. Evaluate the separate VDDIO feature if distinct output voltage domains are necessary for signal integrity optimization.

Part Context

This device belongs to the 9ZML1232E series of clock buffers and muxes from Renesas. It is designed specifically for high-performance server applications where precise clock distribution is critical. The part serves as a derivative of the industry-standard DB1200ZL, ensuring backward compatibility while offering modern low-power characteristics and flexible configuration options through SMBus control.

Replacement Considerations

The 9ZML1232EKILFT is a verified substitute within the same product family, sharing identical functional specifications and pinout compatibility. Both parts serve as DB1200ZL derivatives with 2-input/12-output configurations. Verify that the packaging differences between BKLF and EKILFT do not impact the assembly process or board layout constraints.
