TDA10045H Overview
TDA10045H The TDA10045H is a single-chip channel receiver for 2 and 8 kbytes COFDM modulated signals based on the ETSI specification (ETSI 300-744). The device interfaces directly to an IF signal, which could be either 1st or 2nd IF and integrates a 10-bit Analog-to-Digital Converter (ADC), a Numerically Controlled Oscillator (NCO) and a Phase-Locked Loop (PLL), simplifying external logic requirements and limiting...
TDA10045H Key Features
- 2 and 8 kbytes Coded Orthogonal Frequency Division Multiplexer (COFDM) demodulator (fully DVB-T pliant: ETSI 300-744)
- All modes supported, including hierarchical modes
- Fully automatic transmission parameters detection (including Fast Fourier Transformer (FFT) size and guard interval)
- Digital Signal Processor (DSP) based synchronization (software can be upgraded on the fly)
- No extra-host software required
- On-chip 10-bit Analog-to-Digital Converter (ADC)
- 2nd or 1st IF variable analog input
- Only fundamental crystal oscillator required (4 MHz typical ±100 ppm)
- 6, 7 and 8 MHz channels with the same crystal
- Pulse killer algorithm to protect against impulse noise
