NXP Semiconductors 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 system costs. The TDA10045H performs all the COFDM demodulation tasks from IF signal to the MPEG-2 transport stream.| Part No. | TDA10045H |
