RF Magic Inc. announced two new channel stacking switch (CSS) RF chips for European and Asian digital broadcast satellite (DBS) LNB supply control regulators" target=_blank>low noise block converters (LNBs) and multi-switches. The RF5210 and RF5220 CSS ICs allow LNBs and multi-switches to multiplex multiple channels from DBS satellites onto a single coaxial cable enabling connection to multi-tuner set-top boxes (STBs) and multiple STBs.

The ICs aim to reduce installation cabling complexity and cost for new DBS installations, and are said to provide an upgrade capability for add-on STB installations or replacement multi-tuner STB installations by utilizing existing cabling.

According to Mark Foley, RF Magic's CEO and president, the RF chips are designed to help DBS operators and free-to-air retailers reduce adoption barriers and stimulate consumer demand for more advanced STB and media center electronics that simultaneously process multiple satellite channels.

Designed with a monolithic 6 x 4 cross-point RF switch fabric integrated with three separate RF translators, the RF5210 connects up to three inputs and translates any input channel to any of three output channel assignments. Two RF5210s can be cascaded to input all four bands from one satellite and stack up to six output channels. The RF5220 supports two inputs and two stacked outputs, and two RF5210s 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 three satellites and up to 12 stacked output channels on one cable into a dwelling.
