The TDA10046HT performs all DVB-T channel decoding functions from IF input to transport stream output, using an internal DSP core for synchronization and control.Thanks to its sharp adjacent channel digital ilter, this single-chip receiver achieves excellent performance with low cost tuners (one SAW only). It requires only a low cost crystal oscillator (4 MHz) as a clock source, which can be shared with the tuner.
