QLX111RIQSR

Specialized Overview

The QLX111RIQSR is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the QLx series. It functions as a single-channel receive-side equalizer with extended functionality for advanced protocols operating at line rates up to 11.1 Gb/s. The device supports SMBus (2-wire/I2C) interfaces and operates within a supply voltage range of 1.1V to 1.3V. It is housed in a 16-VFQFN exposed pad package, specifically identified as a 16-QFN (3x3) supplier device package, designed for surface mount installation.

Specialized Feature Summary

• Provides single-channel receive-side equalization capabilities
• Supports advanced communication protocols with high-speed data transmission
• Integrates SMBus interface for configuration and control

Specialized Applications

• Copper cable modules
• Telecommunications equipment
• High-speed data transmission systems

Specialized Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability through authorized distributors is required, as stock may be limited or subject to last-time-buy status. Ensure compatibility with existing design specifications before procurement attempts, considering potential lead time extensions or alternative sourcing channels for end-of-life management.

Specialized Selection Notes

Select this part only if the design requires a 11.1 Gb/s lane extender with specific SMBus control capabilities. Verify that the 1.1V to 1.3V supply voltage aligns with system power rails. The 16-QFN package size must fit the PCB layout constraints. Since the part is obsolete, confirm if the functional requirements can be met by newer generations within the QLx family or other compatible interface solutions.

Specialized Part Context

The QLX111RIQSR is part of Renesas' QLx series, which focuses on specialized interface solutions for high-speed data applications. This specific model addresses the need for signal integrity enhancement in copper-based transmission environments. It represents a niche solution for telecom and industrial applications requiring precise equalization at multi-gigabit speeds.
