OFDM Demodulator
The MC92308 is a Orthogonal Frequency Division Multiplex Demodulator for 2K
transmission mode according to the ETSI specification for digital terrestrial broadcast-
ing (PR ETS 300744). The MC92308 contains all the functionality required to demod-
ulate the information transmitted in one UHF channel.
Feature Summary
Usable for 8MHz/7MHz/6MHz channels by adjusting the clock rate
Digital I/Q separation on-chip
Supports QPSK, 16-QAM and 64-QAM
Supports all guard interval lengths (1/32, 1/16, 1/8, 1/4)
Accepts 8-bit TTL-compatible twos-complement data input
Provides the required control signals for Automatic Gain Control and ADC clock
frequency control
Performs channel estimation and correction by using the embedded pilot carriers
