The GN1158-INTE3Z from Semtech is a multi-rate fiber optic transceiver IC operating from 1.0Gbps to 11.3Gbps, integrating a high-performance VCSEL laser driver and limiting amplifier receiver for SR Ethernet and Fibre Channel applications. Housed in a compact 28-QFN package, this optical transceiver chip covers 1G/10G Ethernet per IEEE 802.3 and 1/2/4/8/10Gbps Fibre Channel data rates. The transmitter section delivers up to 15mA bias current and 20mApp modulation current into 50-ohm differential TOSA with only 5pspp deterministic jitter, while the receiver achieves 5mVppd sensitivity at 11.317Gb/s. Consuming just 180mW typical power, the device integrates a closed-loop Automatic Power Control (APC) for laser aging compensation and comprehensive digital diagnostics monitoring through a 2-wire serial interface, making this multi-rate transceiver IC a complete SFP-module-ready solution.
Application Scenarios
The GN1158-INTE3Z multi-rate transceiver IC is primarily deployed in SFP optical transceiver modules for datacom and telecommunications infrastructure. Key applications include 1G/10G Ethernet SR SFP modules for data center interconnects, Fibre Channel SAN transceivers operating at 1/2/4/8/10Gbps for storage area networks, and telecom access equipment requiring multi-rate optical connectivity. The device serves as the core chipset in optical module designs for switches, routers, servers, and storage systems where VCSEL-based short-reach multimode fiber links deliver cost-effective high-bandwidth connectivity between rack-mounted equipment.
Frequently Asked Questions
Q1: What laser types does the GN1158 support? The integrated driver is optimized for VCSEL lasers in SR (short-reach) applications; for DFB/FP laser-based LR designs, the companion GN1157 delivers 120mA bias and 92mApp modulation capability.
Q2: What supply voltage does the device require? The chip operates from a standard 3.3V supply with 3.3V or 2.5V CMOS-compatible control and status line inputs for flexible host interfacing.
Alternative Models
● GN1158-INE3: The tray-packaged sibling with identical multi-rate SR transceiver specifications, offering 490-piece trays for lower-volume production runs.
● GN1157-INTE3Z: The LR counterpart with DFB/FP laser driver delivering 120mA bias and 92mApp modulation for long-reach single-mode fiber applications in the same 28-QFN package.
● GN1160-INE3: A transmit-only multi-rate laser driver chip from the same family, providing the driver function without integrated receiver for unidirectional optical links.
● GN2108B: Semtech's quad 24-28Gbps transmitter array with integrated ClearEdge CDR and VCSEL array driver for next-generation SR4 parallel optical modules.
