MT352
Data Sheet
Unique algorithms that actively filter out impulse noise, without affecting normal performance, have been
implemented. This reduces the interference effect from vehicles and electrical appliances, which is known to have
significant detrimental effect on the quality of digital TV reception.
Programming is simplified utilizing a high level command driven interface. A sophisticated engine controls all
acquisition and tracking operations as well as controlling the tuner via a 2-wire bus. Any frequency range can be
automatically scanned for digital TV channels. This mechanism ensures minimal interaction, maximum flexibility,
fastest acquisition and the fastest auto scan capability of any chip in the market.
Blind acquisition mode enables automatic detection of all OFDM signal parameters, including mode, guard and
spectral inversion. The frequency capture range is sufficient to compensate for the combined offset introduced by
the tuner and broadcaster.
The device is packaged in a 64 pin LQFP and consumes less than 220 mW of power.
