GN2402-INE3

Overview

The GN2402-INE3 is a four-lane signal conditioner designed for high-speed serial links operating at 10.3125 Gbps. It functions as a repeater or retimer to extend reach and robustness by compensating for transmission losses and resetting crosstalk and jitter budgets. The device features an adaptive equalizer and transmit de-emphasis, requiring no reference clock input. It operates on a single 3.3V supply and is housed in a QFN-44 package. This component targets applications in backplanes, linecards, and active cables within Ethernet and Fibre Channel networks.

Feature Summary

• Four-lane operation at 10.3125 Gbps with adaptive equalization
• Reference-free architecture eliminating the need for external clocks
• Integrated transmit de-emphasis capability
• Single 3.3V power supply requirement

Applications

• nx10G Backplanes
• 10G / 40G Linecards
• 10G / 40G Active cables

Procurement Notes

Verify the specific suffix INE3 against official Semtech documentation to confirm pinout compatibility and environmental ratings. Ensure the source document explicitly lists this exact part number variant before procurement planning.

Selection Notes

Select this component for designs requiring reference-free signal conditioning at 10.3125 Gbps. It is suitable for environments needing jitter budget reset without reference clock infrastructure. Compare power dissipation and footprint requirements against other GN24xx family members if higher data rates are needed.

Part Context
