GN2042-INE3

Overview

The GN2042-INE3 is an integrated bidirectional Clock and Data Recovery (CDR) circuit with a DFB/FP laser driver, designed for low-power SFP+ re-timed optical modules. It operates at data rates from 9.8 Gbps to 11.3 Gbps without requiring a reference clock. The device incorporates an integrated limiting amplifier and jitter filter to ensure compliance with OC-192 standards. It utilizes Semtech’s ClearEdge technology to deliver high-performance signal conditioning and superior eye quality for SONET applications.

Feature Summary

Dual CDR architecture supporting 9.8 to 11.3 Gbps reference-free operation
Integrated DFB/FP laser driver for compact module design
Low power consumption suitable for SFP+ form factors
Integrated jitter filter ensuring robust performance and OC-192 compliance

Applications

SONET optical transceivers
SFP+ re-timed modules
High-speed serial communication links

Part Context

The GN2042 belongs to Semtech’s ClearEdge CDR platform, which targets NRZ signal processing for 10Gbps applications. This family is widely selected for data center optical interconnects, providing low power and small footprint solutions compared to discrete component designs.

Replacement Considerations

Verify pinout compatibility and thermal requirements when substituting. Ensure the replacement supports the specific 9.8–11.3 Gbps range and integrates compatible laser driver outputs for DFB/FP sources.
