DTV signals can reach viewers via local-broadcast, cable, or satellite systems, and consumers who want access to more than one service typically need STBs with different front-end components for each. Trying to cut that complexity, Oren Semiconductor has unveiled three DTV demodulation ICs.

Its OR51122, for U.S. and South Korean markets, is a second-generation eight-level VSB (8-VSB) demodulation solution with an integrated Broadcast Television System Committee stereo decoder and NTSC video demodulation. The OR51132 adds QAM demodulation compliant with ITU-T j.83 Annex B for applications that do not require 8-VSB. The third chip, designated OR51102, offers QAM and NTSC processing.

Reception of local digital broadcasts in the U.S., SDTV or HDTV, requires 8-VSB demodulation. QAM is required for digital cable and NTSC is used for analog TV.

The OR51102, OR51122 and OR51132 are in production now, priced below $20 in 10,000-piece quantities.
