• IC201: Digital DVBT / VIF Demodulator

Part number: MSB1220LQFP
Sharp code: RH-IXC868WJZZY

The MSB1220L is a multistandard analog TV receiver and DVB-T demodulator.  It is fully compliant with the DVB-T 
specifi cation and Nor Dig unifi ed specifi cation. Converts IF differential signals to MPEG-2 transport stream format. It can 
be used in all 2k, 4k and 8 k modes. The device includes a high performance 11 bit A/D converter capable of accepting 
direct IF at 36 or 44 Mhz. A digital fi lter with high rejection capability is also cope with digital or analog adjacent channel. 
The frecuency capture range is suffi cient to compensate for the combined offset introduced by the tuner and broadcaster 
without re-programming the tuner.
It contains a signal processor to offer high quality reception of analog terrestrial multistandard signal.
