QLX4600LIQSR

Specialized Overview

The QLX4600LIQSR is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the QLx series. It is designed for copper cable module applications and features a 46-WFQFN package with exposed pad (46-TQFN(4x7)). The device operates on a supply voltage range of 1.1V to 1.3V and utilizes surface-mount installation. This component serves as a dedicated interface solution within high-speed data transmission systems.

Specialized Feature Summary

• Specialized interface functionality tailored for copper cable modules
• Compact 46-pin Thin Quad Flatpack No-lead (TQFN) packaging for space-constrained designs
• Low-voltage operation supporting efficient power consumption in modern electronic systems

Specialized Applications

• Copper cable module interfaces
• High-speed data transmission equipment
• Telecommunications infrastructure components

Specialized Procurement Notes

Verify the exact suffix LIQSR against official Renesas documentation to confirm pinout and electrical characteristics, as variations exist within the QLX family. Confirm end-of-life status through authorized distributors, as similar models like QLX4600SIQT7 are marked discontinued. Ensure compatibility with existing PCB layouts due to the specific 46-TQFN footprint requirements.

Specialized Selection Notes

Select this component when designing copper-based high-speed interconnects requiring a dedicated interface IC. Compare against other QLx series members to ensure the specific signal integrity and protocol support matches the system architecture. Verify that the 1.1V to 1.3V operating voltage aligns with the target board's power delivery network constraints.

Specialized Part Context

The QLX4600LIQSR is part of Renesas' QLx series, which focuses on specialized interface solutions. It shares the base model number QLX4600 with variants such as QLX4600SIQT7. While specific datasheet details for the LIQSR suffix are not publicly detailed in the provided source material, it functions within the same ecosystem of copper cable module interface controllers.

Specialized Replacement Considerations

Direct substitutes are not explicitly listed in the available public records. Engineers may evaluate the QLX4600SIQT7 or QLX4300SIQSR for functional similarities, though these are also noted as discontinued. A full redesign or qualification of an alternative interface controller from the same manufacturer may be necessary.
