Toshiba Launches Demodulator IC for China Digital Terrestrial and Digital Cable Broadcasts; Achieves high reception performance and low power consumption

TOKYO — Toshiba Corporation (TOKYO:6502) today announced that it has launched a demodulator IC for digital terrestrial broadcasts (GB20600-2006: DTMB) and digital cable broadcasts (GY/T 170-2001: DVB-C) in the Chinese market. Samples are available now with mass production scheduled to start this summer.

The new demodulator IC, TC90518FTG, uses Toshiba’s original multipath[1] cancelling technology and achieves industry-leading-class[2] reception performance under long-delay multipath conditions of +/-300usec. This makes it possible to realize stable reception in environments that may cause a long-delay multipath, such as in single frequency networks (SFN)[3]. The new product also achieves industry-leading[2] low power consumption, 98mW (typ.), which can contribute to lower power consumption by the broadcasting equipment.

1. A reflected wave, mainly caused by structures such as buildings and mountains, that can interfere with reception.
2. As of May 31, 2013. Toshiba data.
3. Single Frequency Network relays broadcast signals using a single frequency. It improves frequency utility but can also cause a long-delay multipath that may lead to reception interference.
