RF Magic Inc. has launched two new low-power Channel Stacking Switch (CSS) RF ICs for the European and Asian digital broadcast satellite (DBS) markets.

The new CSS ICs, the RF5211 and RF5212, are designed to further reduce installation cabling complexity and cost for new DBS installations, and provide a simple upgrade capability for add-on STB installations or replacement multituner STB installations by using existing cabling. The RoHS-compliant chips offer lower power consumption, a key advancement in the technology as deployment throughout Europe and Asia continues to grow.

The low-power ICs are specifically targeted for both operators and free-to-air (FTA) installers and retailers in the single-family home (SFH) LNB market by making satellite TV accessible with one coaxial cable.

The RF5211 and RF5212 follow the RF5210 CSS IC introduced in 2006, which is being increasingly deployed in multidwelling units (MDUs) throughout Europe and Asia. The RF5211 and RF5212 ICs allow low-noise block converters and multiswitches to multiplex multiple channels from DBS satellites into a single coaxial cable. This enables connection to multituner STBs and multiple STBs, said RF Magic.

The RF5211 chip is designed with a monolithic 6x4 cross-point RF switch fabric integrated with three separate RF translators. Thus it can connect up to two inputs and translates any input channel to any of three output channel assignments.

Two RF5211s can be cascaded to input all four bands from one satellite and stack up to six output channels. RF5212 supports two inputs and two stacked outputs and two RF5212 ICs can be cascaded to support all four bands of one satellite and up to four stacked output channels. Other combinations of

these ICs can be designed into LNBs and multi-switches to support up to all four input bands from two satellites and up to nine stacked output channels on one cable into a dwelling.
