9DB1233AGLF

Overview

The 9DB1233AGLF is a PCI Express zero-delay buffer and multiplexer IC manufactured by Renesas Electronics. It operates with a maximum frequency of 166 MHz and features one output channel in a 64-TSSOP package. The device accepts clock inputs and provides HCSL outputs, supporting a 1:12 input-to-output ratio with differential signaling on both sides. It functions within a supply voltage range of 3.135 V to 3.465 V and is rated for an operating temperature between 0°C and 70°C.

Feature Summary

• PCI Express zero-delay buffering and multiplexing capability
• Maximum operating frequency of 166 MHz
• 1:12 input-to-output ratio with differential I/O
• HCSL output signal format

Applications

• PCI Express clock distribution networks
• System board clock generation and buffering
• High-speed digital interface timing solutions

Procurement Notes

Verify the specific suffix 'GLF' against the manufacturer's current documentation to confirm lead-free status and RoHS compliance. Confirm the package designation matches the required 64-TSSOP footprint dimensions. Check for any recent Product Change Notices (PCN) regarding assembly facilities or material updates before finalizing procurement orders.

Selection Notes

Select this component when a single differential clock source requires expansion into twelve matched HCSL outputs for PCIe applications. Ensure the design accommodates the 3.135 V to 3.465 V supply requirement. Verify that the 64-pin TSSOP package fits the available PCB space and thermal constraints for the target operating environment.

Part Context

This part belongs to the 9DB1233 family of clock buffers designed specifically for high-performance computing and communication systems. It serves as a critical timing element in multi-lane PCIe architectures where low jitter and precise phase alignment are required across multiple downstream components.

Replacement Considerations

Consult the official Renesas cross-reference guide for verified pin-compatible alternatives. Do not assume functional equivalence with other buffer families without verifying electrical parameters and pin assignments.
