L2Tek adds advanced adaptive cable equalizer chips from Semtech to its IC portfolio

L2Tek, a manufacturers’ representative and distributor of components and sub-assemblies for professional video and high-speed communications systems, is making available new adaptive cable-equalizer and cable-driver chips that provide the longest full-speed transmission distance for ultra high-definition video systems. Ultra HD is also known as 4K TV and has four times as many pixels as the standard 1920 x 1080 Full-HD.

Developed by Semtech Corporation, a leading supplier of analogue and mixed-signal semiconductors, the new GS6042 and GS6080 are mixed-signal BiCMOS adaptive cable equalizer and cable driver chips, respectively, which are designed to work over 75-Ohm coaxial cables.

The GS6042 delivers the industry’s longest cable reach at 6Gb/s UHD-SDI data rates, and also features best-in-class cable reach at 3G, HD and SD data-rates. To facilitate a simple transition from existing 3Gb/s board designs, the GS6042 is also footprint compatible with Semtech’s existing GS3440 long-reach equalizer.

The GS6080 is the industry’s first 6Gbit/s UHD-SDI cable driver. It forms the industry’s best-performing solution for 6G UHD-SDI connectivity, when used in conjunction with the GS6042 equalizer. As an alternative to the GS6080, the GS6081 also features dual 6G-UHD-SDI outputs.

Both the GS6042 and GS6080 support 6G UHD-SDI, SMPTE* ST 424, SMPTE ST 292 and SMPTE ST 259, and are optimized for performance at 270Mb/s, 1.485Gb/s, 2.97Gb/s and 5.94Gb/s.

Other characteristics of the devices include low power operation – 135mW typical for the GS6080 and GS6081 and 180mW typical for the GS6042 – and an operating temperature range of –40°C to +85°C

The GS6042 and GS6080 are available now from L2Tek in sampling and production quantities.
