Semtech, a supplier of analog and mixed-signal semiconductors, announced that Inneos, a maker of optical subsystems, used its chipset for quad channel SR optical interconnects for a fiber-optic technology demonstration at the 2016 NAB.
The Inneos technology demonstration, utilizing Semtech’s GN1090 and GN1190, featured the multiplexing and demultiplexing of four 12G UHD-SDI video streams onto a single 48Gb CWDM fiber optic link in accordance with SMPTE’s proposed ST 297-2 standard for multi-link 1.5G, 3G, 6G and 12G-SDI over CWDM fiber optic connections.
The GN1090 is a quad channel transimpedance amplifier (TIA) and the GN1190 is a quad channel vertical cavity surface emitting laser driver. This chipset is designed in CMOS technology, enabling performance at low power dissipation and with a high level of integration.
A full suite of on-chip features minimizes external components and speeds up module hardware and firmware development.
Semtech’s UHD-SDI products feature ultra-low power consumption and provides performance at 12Gbps rates. UHD-SDI is ideal for UHDTV infrastructures, including routers, cameras, monitors and switchers.
It is backwards compatible with existing SDI systems and is standardized by both the Society of Motion Picture and Television Engineers (SMPTE) and the International Telecommunication Union (ITU), simplifying UHDTV infrastructure upgrades and reducing risk for broadcasters.
