TDA10045H - NXP

TDA10045H DVB-T channel receiver

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 .

Features

• 2 and 8 kbytes Coded Orthogonal Frequency Division Multiplexer (COFDM) demodulator (fully DVB-T compliant: 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 c.
