Commercialization of ultra-small digital tuner module,
capable of receiving 1-segment digital terrestrial broadcasting signal
in mobile products
Sony Corporation introduces a small-size
digital tuner module, <<BTD-ZJ611>>, capable
of receiving 1-segment digital terrestrial TV broadcasting1
signal and digital terrestrial radio broadcasting2
signal, its sample shipment starting in the beginning of
December this year. In order to achieve applications into
various mobile products, the industry's smallest size of
approx. 20mm x 16mm x 2mm in external dimension and the
industry's lowest power consumption of less than 150mW have
been achieved3.

December/begin, 2003 |
¥50,000 |
As one of the characteristics of digital terrestrial broadcasting
in Japan, using approx. 430kHz of the transmission band
width (i.e. in case of Digital Terrestrial TV broadcasting,
1/13 of the transmission band range) attention is been paid
in the so called 1 segment broadcasting (starting in 2005)suitable
for receiving signal by mobile products in mobile-state.
In <<BTD-ZJ611>> announced this time, advanced
high-frequency·demodulation technology and unique high-density
mounting technology has been compiled, and it is the industry's
smallest, lowest power consuming digital tuner module, fit
to receive signals from 1 segment broadcasting.
1:From December,
2003 onwards, it is scheduled to start in the 3 Major
Regions, (Kanto, Chukyo, Kinki).
2:From October, 2003 onwards, it is scheduled to start
in Kanto and Kinki area.
3:Based on Sony's research as of Sep. 24th, 2003 |
Main Characteristics of <<BTD-ZJ611>>
1. Industry's smallest size
In BTD-ZJ611, in addition to Sony's miniaturization technology
cultivated in the analogue broadcasting tuner, by adopting
Low-IF architecture4, the industry's smallest size of approx.
20mm x 16mm x 2mm in external dimension has been achieved.
From this, it is now possible to implement it into various
mobile products.
2. Industry's lowest power consumption
By adopting Low-IF architecture and others, dramatic reduction
in the circuitry current in the RF (high-frequency) section
has been achieved, also by newly developing the demodulation
algorithm, focused on lowering the power consumption,
the industry's lowest power consumption of less than 150mW
has been achieved. As a result, the ease in introducing
the module into mobile products, whose core is its driving
by battery, has been achieved, enabling long-hours broadcast
viewing/listening.

| 4:Low-IF Architecture. It is a circuitry composition system to convert the RF signal, input from the antenna, to a frequency of a certain low level (= Low-IF). The result is that there is no more need of an external filter which occupies a relatively large volume and, it facilitates removal of image-disturbing signal as well as enabling ease of signal amplification, and also there are advantages that circuitries within the tuner can all be customized at all ranges of frequencies. |
