QLX4600MIBQ15

Specialized Overview

The QLX4600MIBQ15 is a quad receive-side equalizer from the Renesas QLx series, designed for high-speed data transmission applications. It operates on a single 1.2V supply voltage and supports per-channel throughputs up to 6.25Gb/s. The device compensates for frequency-dependent attenuation in copper twin-axial cables, extending signal reach up to 30m on 24AWG cable. It features four independent equalizing filters with 32 programmable compensation levels accessible via serial bus or external control pins. Packaged in a 4mm x 7mm 46-lead QFN, it utilizes Current Mode Logic (I/O) and includes individual lane Loss of Signal (LOS) support.

Specialized Feature Summary

• Quad equalizer design with independently pin-selectable and programmable boost settings
• Supports advanced protocols including DisplayPort v1.2, InfiniBand, and 10GBase-CX4
• Dual configuration method using serial bus interface or external control pins
• Integrated beacon signal support and line silence preservation

Specialized Applications

• QSFP active copper cable modules
• InfiniBand (SDR and DDR)
• 10GBase-CX4
• XAUI and RXAUI
• SAS (20)

Specialized Procurement Notes

Verify the specific suffix 'MIBQ15' against official Renesas documentation to confirm exact package variant and temperature range. Ensure compatibility with 1.2V supply requirements and CML signaling standards. Confirm availability status as distribution listings may vary. Cross-reference pinout diagrams for the 46-TQFN package to ensure correct PCB layout integration.

Specialized Selection Notes

Select this component for high-density data transmission requiring extended reach over copper twin-axial cables. Consider the 32-level programmability for optimal signal fidelity across varying media lengths. Evaluate the trade-off between serial bus complexity and external pin usage for setting compensation levels. Ensure the application environment supports the specified operating temperature range and power supply constraints.

Specialized Part Context

The QLX4600MIBQ15 belongs to the Renesas QLx series of specialized interface ICs. This family focuses on signal integrity solutions for high-speed serial links. The device addresses challenges in copper-based interconnects by providing adjustable equalization. It complements other Renesas components in server and storage infrastructure designs.

Specialized Replacement Considerations

Check for direct substitutes within the QLx series offering similar quad-equalizer functionality. Verify if alternative packages or temperature grades are available from Renesas. Ensure any replacement maintains compatibility with 6.25Gb/s data rates and 1.2V operation.
