Marvell Demodulates DVB-T, DVB-C, NTSC/PAL/SECAM signals from terrestrial and cable networks

Marvell Demodulates DVB-T, DVB-C, NTSC/PAL/SECAM signals from terrestrial and cable networks.

The 88DE8020 and 88DE8025 are single chip hybrid demodulator ICs for Digital Video Broadcasting (DVB) and analog video broadcasting worldwide.

Marvell® has launched the first devices in a family of solutions that it is developing for worldwide TV Radio Frequency (RF) sub-systems. The 88DE8020 and 88DE8025 are single chip hybrid demodulator ICs for Digital Video Broadcasting (DVB) and analog video broadcasting worldwide. The new devices demodulate Intermediate Frequency (IF) signal from the hybrid tuner and generate Digital Transport Stream and Analog Composite Video with Sound Intermediate Frequency (SIF). The Marvell-designed integrated RF sub-system enables TV makers to develop a single TV controller chassis for worldwide needs and localize it with region specific tuners and demodulators.

Measuring only 7 mm x 7mm, the Marvell 88DE8020 features very high level integration for the demodulation of Digital Video Broadcasting – Cable (DVB-C), Digital Video Broadcasting – Terrestrial (DVB-T) (Annex A and C) and NTSC/PAL/SECAM. The high level of integration in the Marvell 88DE8020 enables TV manufacturers to develop RF subsystems that have lower cost, lower power and a slimmer profile.

Typically, TV makers need to provide multiple SAW filters, and separate analog and digital demodulators for integrated digital televisions (iDTVs) that support hybrid terrestrial and cable networks in DVB countries. The 88DE8025 is a pin-compatible subset of the 88DE8020 supporting analog and DVB-T demodulation for applications that do not require DVB-C.

According to Dr. Nikhil Balram, Vice President and General Manager of the Digital Entertainment Business Unit, Communications and Consumer Business Group at Marvell demodulator performance is one of the critical blocks for an immersive viewing experience for digital television sets: "We believe the Marvell 88DE80xx solutions for worldwide RF sub-system market enables robust reception under varying signal conditions like multi-path, adjacent and co-channel interference and impulse channel noise while achieving lower cost and lower power through our higher integration."

The Marvell 88DE802x parts will be shipping in the first calendar quarter 2010. Samples are available today and may be requested by using the more information service provided below.
