ALPS Electric Europe unveils the TSVN Series Full Segment Digital Terrestrial TV (ISDB–T) Tuner for automobiles that is said to be the smallest and the first surface mount type automotive tuner.

 TSVN Series

In addition to characteristics so far demanded of automotive RF equipment, namely high-sensitivity reception and resistance to noise created, for example, by electric mirrors, there is a growing requirement for automotive TV tuners which consume low levels of power to make them suited to hybrid and electric vehicles. TV tuners built into car navigation systems, too, need to be more compact and require a smaller mounting area than ever before since greater sophistication of systems, such as incorporation of Wi-Fi and other technologies, has led to a larger number of components.

As the industry's first surface mount, 4-diversity type full segment tuner, the TSVN Series contributes to automation in the production lines of car navigation system manufacturers. In addition, power consumption has been reduced to 1.55W, a 30 per cent improvement on earlier models, realising the low power consumption demanded for use in electric and other environmentally friendly vehicles.

RF circuit technology acquired by ALPS over the years was applied to the TSVN Series to reduce interference between circuits, thereby enhancing immunity to ITS interference and resistance to various types of noise while allowing a compact size of 23.0 × 25.0 × 3.1mm. The mounting area is 70 per cent smaller, and volume 85 per cent smaller, than earlier models.

This ISDB–T tuner also has the highest receiving sensitivity in the industry, claims ALPS. To ensure stable reception during actual use, circuitry has been optimised through feedback from repeated road tests into circuit design. Mass production is already underway.
