DBS Outdoor Unit Solutions
Our DBS outdoor unit solutions simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. This capability is critical to allow a satellite receiver to enable picture-in-picture viewing or to record and watch two or more programs simultaneously using a single cable. In cable TV systems, all the channels are available over the coax connected to the TV set or the cable STB. In satellite systems, the number of channels available from multiple satellites typically exceeds the channel carrying capabilities of the connecting cable.
Entropic's Channel Stacking Switch (CSS) and Band Translation Switch (BTS) technologies are designed to select desired satellite channels and re-arrange them for delivery to the indoor STB over a single connecting cable. This single cable connects the outdoor unit to either many STBs in and around the home or a media center inside the home, and delivers all the programs being viewed on the various devices inside the home.
The implementation of such complex RF processing in an integrated RFIC requires Entropic's unique RF system architecture and design capabilities, including the design of multiple, independently operable, low noise oscillators on a single die, cross-point switching and high isolation techniques realized in both circuit design and advanced floor planning methodologies.
