Marvell

The Marvell 88DE8020 and 88DE8025 hybrid demodulators with integrated ClearRF™ technology enable robust TV reception under complex signal impairment conditions in terrestrial and cable networks. The demodulators are compatible with typical low/high IF tuners and TV decoders. The 88DE8020 supports DVB-C/DVB-T/NTSC/PAL/SECAM demodulation, while the 88DE8025 supports DVB-T/NTSC/PAL/SECAM demodulation. Both devices can demodulate 2K and 8K COFDM modulated signals based on the ETSI specification (ETSI EN 300 744) and QAM modulated signals based on the DVB-C specification (ETSI EN 300 429). They can also be programmed to demodulate analog NTSC/PAL/SECAM TV inputs and output CVBS and Sound IF signals.

Applications

The hybrid demodulator when combined with a hybrid CAN tuner or silicon tuner can be used as a standalone frontend board in a variety of applications including:

• Digital Televisions (DTV)
• Digital set-top boxes, video recorders
• Network interface modules
• PC Tuner cards and sticks

To shorten system manufacturers’ design cycles and accelerate time-to-market, Marvell provides complete DTV front-end development platforms and reference designs with device drivers, schematics, layout files and other documentation, including detailed Nordig, D-Book and E-Book test results.
