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 cancelling technology and achieves industry-leading-class 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). The new product also achieves industry-leading low power consumption, 98mW (typ.), which can contribute to lower power consumption by the broadcasting equipment.
Part Number TC90518FTG Supply Voltage Internal core: 1.1Â±0.1V, I/O block: 3.3Â±0.3V Package VQFN64 9mm x 9mm x 0.9mm DTMB demodulation "¢ Supports all 330 DTMB modes "¢ Built-in multipath canceller DVB-C demodulation "¢ Auto detection of symbol rate, modulation format, spectrum polarity "¢ Supports 0.5~7.5Mbaud symbol rate Interface "¢ Input :IQ baseband, low IF, standard IF "¢ Output: serial and parallel MPEG-2 transport stream
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.
