TDA10046HT
Single-chip DVB-T channel
decoder
Delivering a low cost system solution for DVB-T channel
decoding, the TDA10046HT single chip channel decoder
demonstrates Philips Semiconductors’ continuing leader-
ship 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.
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.
A common phase error
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
Key features
• 2K and 8K COFDM demodulator, fully ETS 300-744 compliant
• TPS and Cell Identiier2I C-bus readable
• 2nd or 1st IF analog input
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 scan of the whole UHF/VHF band, and fast zapping facilities.
• On chip 10-bit ADC and PLL
Evaluation boards are available with most commercial tuners.They are
• Single or dual AGC loop (with programmable takeover point)
provided with all the necessary software including a tailored Graphical
• Adjacent channel digital iltering (only one external SAW ilter is required)
User Interface (GUI) that allows easy evaluation and development.
• Automatic frequency offset detection (±1, 2 or 3 standard offsets)
