GN2412BIBE3

Overview

The GN2412BIBE3 is a twelve-lane retimer from the GN2412 Family, designed for high-speed serial link applications. It supports full-rate operations from 5Gbps to 12.8Gbps and extends functionality to half-rate and quarter-rate modes down to 1.25Gbps. The device compensates for transmission medium losses and reflections while resetting crosstalk and jitter budgets. Key electrical parameters include a 0.9V core supply and a 1.8V I/O supply. Power dissipation varies by speed: typical values range from 205mW/channel at 8Gbps to 250mW/channel at 12.8Gbps for the A3 variant.

Feature Summary

• Twelve-lane repeater/retimer supporting 5Gbps to 12.8Gbps full-rate operation
• Supports half-rate and quarter-rate operation down to 1.25Gbps
• Adaptive linear input equalization combined with adaptive multi-tap DFE
• Multi-tap output de-emphasis and programmable output swing

Applications

• Ethernet (IEEE 802.3ba compliant)
• InfiniBand (SDR/DDR/QDR compliant)
• Fiber Channel
• 10GBASE-KR link training

Procurement Notes

Verify the specific suffix 'IBE3' against official Semtech documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with IEEE 1149.1 and 1149.6 JTAG boundary scan requirements if testing infrastructure relies on these standards.

Selection Notes

Select this component for designs requiring twelve lanes of signal conditioning in dense backplane or linecard environments. Consider the A2 or A3 power variants based on thermal constraints, as dissipation ranges from 205mW to 265mW per channel depending on data rate. Verify support for up to two input reference clocks and required latency specifications.

Part Context

The GN2412BIBE3 belongs to the GN2412 Family of multi-lane signal conditioners. This family is engineered to enhance the reach and robustness of high-speed serial links by addressing signal integrity issues such as loss, reflection, crosstalk, and jitter in complex interconnect systems.
