The MSB1230 is a single chip demodulator supporting DVB-T2 and DVB-T standards. The MSB1230 enables the
design of ETSI EN302755 compliant receivers with performance exceeding DTG Dbook 6.1 requirements. The
device integrates a house keeping microcontroller that takes care of all real time and algorithmic tasks
simplifying the host control interface.
requirements for adjacent channel interference. The MSB1230 may be clocked directly using a crystal,
typically 24MHz or may take a reference clock from another stable source such as the tuner.

The MSB1230 front end can accept tuners that provide IF, low IF or ZIF output. A high rejection channel filter
has been included easing the channel filtering requirement of the tuner whilst still meeting the stringentrequirements for adjacent channel interference. The MSB1230 may be clocked directly using a crystal,
typically 24MHz or may take a reference clock from another stable source such as the tuner.
The MSB1230 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 alltypical 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 ofOFDM digital TV reception.
