Tuners for terrestrial broadcasting are
compact
Alps has developed the industry's smallest series of tuner units for digital terrestrial broadcasting. The newly developed TDQ Series also can be used as an analogue broadcasting receiver.
Digital terrestrial broadcasting began in Japan in December 2003 and continues to receive growing acceptance worldwide The addition of digital broadcasting to conventional analogue broadcasts has led to the coexistence of two different broadcasting methods

TACT switches slim to compact applications
Alps Electric has released the industry's thinnest double-action TACT switches for applications such as shutter buttons for digital still and video cameras.
Detector switches seek automotive applications
The SPVQ4 Series comprises waterproof, high-contact-reliability detector switches that have a long stroke and can withstand severe conditions.
Given these circumstances, televisions and other devices require both digital and analogue tuners to receive each broadcast.
Responding to this opportunity, Alps has developed a single digital terrestrial broadcasting unit, the industry's smallest, that can also be used as an analogue broadcasting receiver.
Currently, TVs and DVD recorders require separate digital terrestrial broadcasting and analogue broadcasting tuners as well as an airwave distribution device in order to receive both digital and analogue broadcasts.
This requires significant space, an added inconvenience.
Utilising its proprietary engineering technology and expertise accumulated over many years, Alps has developed an ultra-compact single-unit tuner that can receive both digital terrestrial and analogue broadcasts, which in turn contributes to more compact and thinner set devices.
Using an Inter Integrated Circuit (I2C) bus controller allows set manufacturers to freely specify signal start levels, as output signal levels can be regulated with RF automatic gain control (AGC) even when input signal levels are changed.
This enables the control of varying field intensities that occur according to regions, making it easy to adjust settings by regions.
Furthermore, by utilising custom IC, which is made possible through Alps' proprietary high-frequency circuit technology, wide dynamic range and low phase noise can be attained.
Through wide dynamic range, a widely variable level of RF-AGC settings is possible.
In addition, low phase noise enables the reception of crisp digital images even when electrical fields are weak.
Moreover, the environment-friendly design includes a power saving mode that lowers consumption of electricity, contributing to the reduction of CO2 emissions.
