MT5133 DATA SHEET
General Description
1. Introduction
MT5133 is Media Tak’s 2
nd
generation COFDM (Coded Orthogonal Frequency
Division Multiplex) channel demodulator for DVB-T receiver. It is fully compliant with
the DVB-T specification (ETSI 300744) and Nordig Unified. MT5133 implements the
functions from tuner IF out to MPEG-2 transport stream input. The device can support
2K, 4K or 8K mode with 6, 7, 8MHz channel. By integrating high performance A/D
converters into the chip, MT5133 can accept first or second IF signal from
conventional tuner thus eliminating the need for an external down-converter. Pure
digital synchronization, advance channel estimation and equalization guarantee the
wide acquisition range of MT5133. User can easily access on-chip information,
including signal-to-noise ratio, Bit Error Ratio (BER) before and after Viterbidecoder.
Serial or parallel MPEG transport stream output can be interfaced to all commonly
available backend processor chips.
