Semtech has announced production of its chipset for quad channel SR optical interconnects operating from 1 to 14.5Gb/s. The GN1090 is a quad channel TransImpedance Amplifier (TIA) while the GN1190 is a quad channel vertical cavity surface emitting laser driver.
The chipset is designed in leading edge CMOS technology, enabling industry-leading performance at low power dissipation with a high level of integration. A full suite of on-chip features minimises external components and serves to speed up customers’ hardware (and firmware) development. The GN1090 and GN1190 offer developing optical modules, active optical cables and optical interconnects best-in-class link performance, high flexibility and lowest overall solution cost.
The chipset’s comprehensive digital circuitry implements a complete set of alarms and monitoring, which simplify module-level firmware design and enable the use of cost-effective MCU. In addition, adjustable equalisation simplifies PCB design and optimises performance to any host system electrical interface. The GN1090 gain and signal integrity features, combined with the excellent input sensitivity, eliminate the need for additional post amplification in the module and make it suited for SR as well as LR optical interconnects.
The GN1090 and GN1190 chipset operates from 1 to 14.5Gb/s, making it suitable for a wide variety of industrial and commercial applications in data centre, manufacturing and consumer markets. The advanced integrated test features simplify module development costs and reduce overall production test costs.
Timothy Vang, Senior Director, Datacom Marketing, Signal Integrity Product Group, Semtech, commented: “The GN1090 and GN1190 chipset has been an overwhelming success for Semtech and our customers. The performance and feature set of the GN1090 and GN1190 have enabled our customers to quickly bring to market leading solutions for 40Gb/s QSFP+ and Active Optical Cables (AOCs) for data centres and a wide range of other applications.”
The GN1090 and GN1190 are in full production now.
