The lowest system solution cost can be achieved by using silicon tuners that:
• Eliminate redundant circuits in other silicon tuners but also present in the SOC
• Offer an ultra-small die size in the lowest cost process
As shown in Figure 6, Fresco’s Simply RF™ silicon tuners are one example of the latest silicon tuners which interface with the most popular TV SOCs to achieve lower system costs.

Outlook for silicon tuners in television
Industry experts predict exponential growth for silicon tuner adoption inside the TV for the foreseeable future in CAN tuner and on-board designs. The market for TV silicon tuners will continue to expand with increased consumer demand for multi-screen support on a wide variety of consumer devices including traditional TV sets, PCs, tablets, and mobile phones.
Industry-wide consolidation underscores the importance of delivering the lowest cost solution at the optimal performance to meet market requirements. More functions will be integrated into the TV SOC as technology advances and the most cost-effective implementations are realized in the digital domain. At the same time, there is greater demand for ultra-simple tuners that complement rather than duplicate SOC system functionality. While transitions in the television industry can take time, with fewer SOC manufacturers, the migration to the latest SOC architectures and simplified tuners is already well underway and expected to grow rapidly in the years to come.
