QLX4270RIQT7

Specialized Overview

The QLX4270RIQT7 is a specialized integrated circuit interface component manufactured by Renesas Electronics Corporation, belonging to the QLx series. It functions as a settable quad receive-side equalizer designed for DisplayPort applications. The device compensates for frequency-dependent attenuation in copper cables, enabling operation on ultra-thin gauge wiring such as 40AWG. It operates on a single 1.2V power supply and supports per-channel throughputs of up to 2.7Gb/s using current mode logic (CML) inputs and outputs. The component is housed in a compact 46-lead QFN package with dimensions of 4mm x 7mm.

Specialized Feature Summary

• Independent pin selection and programmability for each equalizer boost setting
• Extended functionality specifically tailored for DisplayPort signal integrity
• Supports operation on ultra-thin 40AWG copper cables to extend reach

Specialized Applications

• DisplayPort adaptors and repeaters compliant with VESA DisplayPort Standard v11a
• High-density data transmission systems requiring active copper cable assemblies
• Applications utilizing thinner gauge copper cabling to maximize physical reach

Specialized Procurement Notes

Verify component authenticity and datasheet revision status prior to integration. Confirm that the specific package variant matches the required PCB footprint. Ensure design compatibility with the 1.2V supply voltage and CML signaling levels specified for this interface controller.

Specialized Selection Notes

Select this component when designing DisplayPort interfaces requiring extended cable reach over thin-gauge copper. It is suitable for high-density applications where space constraints necessitate a small form factor. Ensure the system architecture supports the required 2.7Gb/s per-channel throughput and CML input/output standards.

Specialized Part Context

This part belongs to the QLx series of specialized interface controllers from Renesas. It shares the same 46-TQFN(4x7) package and 1.2V operating voltage profile as other members like the QLX4600SIQT7. While functionally similar in packaging, it is distinctively optimized for DisplayPort equalization rather than general copper cable module interfacing.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Renesas resources for potential obsolescence management or alternative QLx series components.
