GN1158-INTE3Z

Overview

The GN1158-INTE3Z is a multi-rate transceiver IC designed for Short Reach (SR) Ethernet and Fibre Channel applications, supporting data rates from 1.0 Gbps to 11.3 Gbps. It integrates a VCSEL laser driver with a maximum bias current of 15 mA and a limiting amplifier receiver. The device features integrated closed-loop Automatic Power Control (APC), programmable Tx eye shaping, and input/output equalization. It includes digital diagnostics via a two-wire serial interface and operates on 3.3 V or 2.5 V CMOS logic. The component is housed in a 28-pin QFN package measuring 4 mm x 4 mm.

Procurement Notes

Verify the specific ordering code suffix against official Semtech documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with host system voltage levels and I2C/SMBus interfaces. Confirm that the 28-pin QFN footprint matches the design layout. Validate RoHS compliance status through the manufacturer's current certification records before finalizing procurement.

Selection Notes

Select this component for short-reach optical interconnects requiring integrated transmitter and receiver functionality. It is suitable for systems needing support for multiple standard data rates within the 1.0 to 11.3 Gbps range. Consider its low power consumption and integrated APC when designing compact optical modules. Ensure the application environment supports the required CMOS control voltages and serial communication protocols.

Part Context

This part belongs to Semtech’s Gennum portfolio of high-performance optical communication ICs. It is engineered for data center and telecommunications infrastructure where cost-effective, high-speed optical connectivity is essential. The GN1158 series addresses the demand for flexible, multi-rate solutions in evolving network standards.

Replacement Considerations

Check for direct pin-to-pin replacements such as the GN1158-INE3 variant, which shares the same package but may differ in reel packaging. Verify functional equivalence with other multi-rate SR transceivers if supply constraints exist.
