DESCRIPTION
The TDA10045 is a single chip channel receiver for 2K and 8K COFDM modulated signals based on the ETSI specification (ETSI 300 744). The device interfaces directly to an IF signal, which could be either first or second IF and integrates a 10-bit AD converter, a NCO and a PLL, simplifying external logic requirements and limiting system costs.

FEATURES
• 2K and 8K COFDM demodulator (Fully DVB-T compliant : ETS 300-744).
• All modes supported including hierarchical modes.
• Fully automatic transmission parameters detection.
• DSP based synchronization (upgradability).
• No extra-host software required.
• On chip 10-bit ADC.
• 2nd or 1st IF variable analog input.
• Only fundamental Crystal oscillator needed.
• Frequency offset estimator to speed up the scan.
• RF Tuner input power measurement
• Parallel or serial transport stream interface.
• On chip FEC decoder.
• BER measurement (before and after Viterbi decoder)
• SNR estimation
• TPS bits I2C readable (including spare ones)
• Channel frequency response output.
• Controllable dedicated I2C tuner bus (5V tolerant).
• 2 low frequency spare DAC. (∆Σ)
• Spare I/O.
• CMOS 0.2µm technology.

APPLICATIONS
• DVB-T fully compatible.
• Digital data transmission using COFDM modulations.
