This demodulator supports ISDB-T (Terrestrial Digital broadcast standard), DVB-T(ETSI EN 300 744 standard) and DVB-T2 in a single SoC Chip, and high performance 10-bits ADC is integrated for DVB-T, ISDB-T and DVB-T2 demodulation, and a shared AGC, which support both single-loop and dual loop, can be flexible with a variety of RF tuners. ISDB-T demodulation fully compliant ARIB STD-B31(ISDB-T), and low power consumption receiver for receiving digital terrestrial broadcasting based on the Integrated Services Digital Broadcasting Terrestrial Television System(ISDB-T). Through the Serial or Parallel TS Interface, output the MPEG-2 / H.264 Transport Signal. ISDB-T demodulation integrate, and flexible down converter function, so, support zero- IF(Direct Conversion) signal , low-IF(about 5MHz). ISDBT demodulator has fully high performance digital signal processing algorithm for all kind of transmission mode and parameters ISDB-T signals, also can demodulate the digital terrestrial sound broadcast. And support fixed and portable reception.
