This document mainly introduces the application of MOTOROLA MC92314 DVB-T single chip demodulator
The document provides a comprehensive technical guide for the Motorola/Freescale MC92314 Single Chip DVB-T Demodulator. It outlines the chip's capabilities within the DVB-T standard, including support for QPSK, 16-QAM, and 64-QAM modulation schemes, as well as automatic lock onto various guard interval lengths.
The guide details the internal architecture of the device, specifically the OFDM demodulator block and the Forward Error Correction (FEC) block. It includes extensive information on pinouts for both QFP and BGA packages, I2C register maps, tuner interface characteristics, and initialization procedures to speed up acquisition time.
