Entropic Communications Inc. has released its next-generation channel stacking switch (CSS) products used in single-cable satellite installations. The RF5218 and RF5219 ICs have been specifically designed to address the low power requirements of the European digital broadcast satellite (DBS) market.

The channel stacking switch ICs reduce both the cost and the cabling complexity of DBS installations. Unlike traditional satellite installations, which require a unique cable for each tuner from the satellite dish to the STB, Entropic's CSS solutions enable multiple video streams from individual or multiple satellites into the home over a single cable. This simplified cabling architecture enables the deployment of STBs, with multiple tuner capabilities, in multiple rooms without expensive installation or retrofitting. The Channel Stacking technology also enables plug and play for STB upgrades and allows all levels of installers, from professional to consumers, to reuse existing cabling to quickly setup a DBS system.

Energy efficient solutions
The RF5218 and RF5219 devices were designed to both reduce power consumption and increase performance of the single cable solution, said Entropic. The Channel Stacking Switch ICs, embedded in a low noise block (LNB) or multi-switch, consume up to 40 percent less power than previous generations and can support up to 12 tuners, with power sharing, down a single coaxial cable.

RF5218 and RF5219 require are low power and are specifically designed for both operators and free-to-air installers and retailers in the direct-to-home outdoor unit market. Both generations of CSS solutions allow LNB converters and multi-switches to multiplex multiple channels from DBS satellites onto a single coaxial cable enabling connection to digital video recorders and multiple STBs.

Products based on Entropic's Channel Stacking Switch technology will be showcased at IBC 2007 on September 7-11, in Amsterdam, The Netherlands.
