MSB1236C MSTAR LQFP48

The MSB1236C is a single chip demodulator supporting DVB-T2 and DVB-T standards. The MSB1236C enables the
design of ETSI EN302755 compliant receivers with performance exceeding DTG Dbook 7.0 requirements. The
device integrates a house keeping microcontroller that takes care of all real time and algorithmic tasks simplifying

the host control interface.

The MSB1236C front end can accept tuners that provide IF, low IF output. A high rejection channel filter has been
included easing the channel filtering requirement of the tuner whilst still meeting the stringent requirements for

adjacent channel interference. The MSB1236C may be clocked directly using a crystal, typically 24MHz.

The MSB1236C is capable of blind acquisition of DVB-T and T2 signals. All parameters may be detected in this

mode enabling fast and accurate auto scanning. Its frequency recovery circuit is capable of compensating for all

typical tuner and broadcast frequency errors.

For DVB-T, a novel impulsive interference filter has been implemented to remove impulsive interference without
affecting normal operation thus reducing the effects of transient interference known to affect the quality of OFDM
digital TV reception.
