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.
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.
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
