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. CG_GP1Q can be used in    either 2K or 8K modes with 6, 7 or 8MHz channels and is capable of addressing all modes of transmission.

CG_GP1Q includes a high performance 10-bit A/D converter capable of accepting direct IF at 36.17 or 43.75MHz.   Sampling rates required for both these frequencies in 6,7 or 8MHz OFDM channels can be generated from a single 20.48MHz crystal.

Alternatively, there is provision to replace CG_GP1Q with a 4 or 27MHz external clock input.
