Description

MT352 is a superior third generation Coded Orthogonal Frequency Division Multiplex (COFDM) television demodulator that is both Nordig II and DVB (as defined in ETS 300 744 specification) compliant. MT352 can be used in either 2 K or 8 K modes with 6, 7 or 8 MHz channels and is capable of addressing all modes of transmission.

MT352 includes a high performance 10-bit A/D converter capable of accepting direct IF at 36.17 or 43.75 MHz. Sampling rates required for both these frequencies in 6,7 or 8 MHz OFDM channels can be generated from a single 20.48 MHz crystal. Alternatively, there is provision to replace this crystal with a 4 or 27 MHz external clock input.
