RF Magic has introduced a tuner IC called RF4800, which is developed for standard DVB-C (Digital Video Broadcasting over Cable) in Europe, Asia, Australia and South Africa.RF Magic, in collaboration with STMicroelectronics, has certified the entire firmware of the DVB-C silicon tuner to interact with ST's latest video demodulator and integrated MPEG decoder and demodulator.
Based on RF Magic's AdaptiveTuneTM technology, the RF4800 product includes all the necessary front-end features and does not require an external SAW filter or amplifier. In addition, AdaptiveTune technology allows software to program important tuner settings and thus optimize front-end performance in different environmental conditions.
The STV297E involves a very compact DVB-C single-chip transceiver that consumes very little power and can convert ZF difference signals or baseband difference signals for QAM carriers (Quadrature Amplitude Modulation) in MPEG-2 blocks. . The STV297E meets the DVB-C specification (EN 300 429) and the NorDig unified specification.
The NorDig compatibility test has been performed and companies can immediately provide reference designs that are ready for use in production.
