Sony to launch 40 new Eco-Friendly Silicon TV Tuner
Sony will launch 40 new small silicon tuner modules that are compatible with worldwide broadcast systems.
Available in three different series with the SUT-Rx200 Series (silicon Tuner), the SUT-Dx200 Series (silicon tuner with demodulator), and the SUT-Rx300 Series (slim silicon Tuner), these new tuners reduce the number of necessary components, and are introduced as Eco-Friendly with low power consumption (40% less than Sony’s conventional coil tuner).
Sony also claims that their tuners are 40% smaller than conventional coil tuner. Lastly, these tuners should provide a more stable reception by excluding air-core coil.
In light of the market’s transition from coil to silicon tuners, Sony will build up a global business by launching 40 small, high-performance silicon tuner modules, which incorporate its proprietary radio frequency circuit technology.
In order to meet customers’ various demands, Sony has developed different types of silicon tuner modules including antenna switch models, loop-through function,demodulator models for digital broadcasts, and dual tuner models.
By using Sony’s silicon tuner modules, LCD TV and Video recording equipment manufacturers can realize improved production efficiencies, while being assured of superior performance. For example, they can reduce the number of necessary components as well as implement common global design for both hardware and software. Sony’s silicon tuner modules are also eco-friendly with low power consumption (40% less than Sony’s conventional coil tuner) and standby mode. In addition, they are immediately compatible with new broadcast systems such as, “DVB-T2″* (Digital Video Broadcasting – Terrestrial 2).
Sony started mass production of silicon tuner modules in 2008 and has cumulatively produced more than 10 million modules (as of June 2010).
Reduced size of silicon tuner module by 40% compared to conventional coil tuner which contributes to smaller printed circuit board in final products.
Superior Interference Tolerance
Silicon tuner module is designed to withstand ingress noise from peripheral circuits because it uses Sony’s proprietary radio frequency circuit and simulation technologies.
In addition, spontaneous-emission noise can be minimized, which simplifies product development.
Stable reception performance
Achieved stable reception in silicon tuner module by excluding air-core coil. Doing so minimizes the variations caused by reception channels and by the usage environment (ex. ambient temperature).
Furthermore, minimized the performance variation of each product relative to conventional coil tuner.
Silicon tuner module uses 50mW in standby mode and contributes to low power consumption for final products.
