• High-speed signal equalization in server backplanes

Specialized Procurement Notes

This component has been officially declared obsolete by the manufacturer, with end-of-life notifications recorded in January 2022. Availability is restricted to existing stock or secondary market sources. Verification of authenticity is critical due to the discontinued status. Buyers should confirm the specific tape-and-reel packaging details and ensure compliance with current environmental regulations such as RoHS3 before integration into new designs.

Specialized Selection Notes

Designers requiring quad lane extenders for copper interconnects should consider this part for legacy systems. The 46-pin QFN footprint requires careful PCB layout consideration for thermal dissipation and signal integrity. Since the part is discontinued, alternative sourcing strategies must be evaluated. Engineers should verify that the 1.1V to 1.3V operating range aligns with their target system power delivery infrastructure.

Specialized Part Context

The QLX4600LIQT7 is part of the QLx family of high-speed interface devices produced by Renesas Electronics. This series focuses on extending data transmission capabilities over copper media. The LIQT7 suffix denotes the specific temperature grade and packaging variant within the broader QLX4600 product line, which includes various pin-compatible options for different application requirements.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the QLX4600LIQT7 is obsolete, engineers must evaluate functional equivalents from other manufacturers or newer generations of Renesas products that support similar copper cable module applications.
