Toshiba launches Demodulator IC

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 multipath1 cancelling technology and achieves industry-leading-class2 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-leading2 low power consumption, 98mW (typ.), which can contribute to lower power consumption by the broadcasting equipment.
