TDA10046HT Delivering a low cost system solution for DVB-T channel decoding, the TDA10046HT single chip channel decoder demonstrates Philips Semiconductors’ continuing leadership in digital broadcast reception, offering advanced features such as adaptive echo cancellation, fast channel scanning and a unique ‘Pulse Killer’ algorithm that reduces impulsive noise disturbances. Single-chip DVB-T channel decoder Semiconductors 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. After sampling of the 1st or 2nd IF by a 10-bit ADC, the signal is converted to baseband and passes through the FFT demodulator. Channel frequency response is then estimated and iltered in both time and frequency domains, and used to equalize the signal. correction handles tuner phase noise. The TDA10046HT implements a number of advanced features including a high-performance ‘Pulse Killer’ algorithm to reduce the disturbing effects of short and strong impulsive noise interference caused by electrical domestic devices and/or car trafic. For maximum ease of use, the TDA10046HT features fully automatic transmission parameters detection, ultra fast s……
