Highly Integrated Switch Matrix Solutions for Fast Growing Satellite and Cable Television Markets

Thu, 09/30/2010 - 10:53am


Skyworks Solutions, Inc. recently announced that it has launched several new complementary metal-oxide semiconductor (CMOS) switch matrix devices for the direct broadcast satellite (DBS) and cable television markets.

Skyworks’ newest solutions eliminate the need for external components by integrating critical functionality directly on the CMOS die, providing customers with significant cost savings and reduced printed circuit board (PCB) space requirements.

DBS is a service that allows households to receive television programming directly from a satellite transponder via a low noise block converter.  Across the satellite receiver industry, low noise block switches are increasingly enabling a single dish to view multiple satellites and allow hundreds of channels to be viewed per household.

Skyworks’ switch matrix solutions connect four of the satellite signals to two indoor set-top boxes selectable by the viewer’s channel choice. Current Skyworks’ customers include BSkyB, DIRECTV, EchoStar and their design partners - along with a variety of emerging Chinese LNB original equipment manufacturers and original device manufacturers.

The SKY13327-365LF and the SKY13369-365LF are 0.25 to 2.15 gigahertz (GHz) 4 x 2 millimeter (mm) switch matrices that combine a digital decoder with the RF switching network, tone/voltage detect and digital satellite equipment control rejection (DiSEqC) functionality.

The compact 20-pin quad flat no lead (QFN) packaged switches enable any of the four inputs to either of the two outputs. Switch states can be selected using tone and voltage signals together with vertical-horizontal mirror control inputs. The switches are packaged in Skyworks’ Green and restriction of hazardous substances (RoHS)-compliant, leadless plastic packages.
