Single chip hybrid demodulators for integrated digital televisions from Marvell

Marvell has announced the 88DE80xx family of hybrid demodulators. The 88DE8020 and 88DE8025 are the solutions for worldwide TV Radio Frequency (RF) sub-systems, and they are single chip hybrid demodulators for Digital Video Broadcasting (DVB) and analog video broadcasting.

The 88DE8020/88DE8025 demodulate Intermediate Frequency (IF) signal from the hybrid tuner and generates Digital Transport Stream and Analog Composite Video with Sound Intermediate Frequency (SIF). The Marvell integrated RF sub-system is designed to enable TV makers to develop a single TV controller chassis for worldwide needs and localize it with region specific tuners and demodulators.

The 88DE8020 features very high-level integration for the demodulation of Digital Video Broadcasting - Cable (DVB-C), Digital Video Broadcasting - Terrestrial (DVB-T) and NTSC/PAL/SECAM. And the 88DE8025 is a pin-compatible subset of the 88DE8020 supporting analog and DVB-T demodulation for applications that do not require DVB-C. 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.

"Demodulator performance is one of the critical blocks for an immersive viewing experience for digital television sets," said Dr. Nikhil Balram, Vice President and General Manager of the Digital Entertainment Business Unit, Communications and Consumer Business Group at Marvell Semiconductor, Inc. "We believe the Marvell 88DE80xx solutions for worldwide RF sub-system market to enable our customers to achieve robust reception under varying signal conditions like multi-path, adjacent and co-channel interference and impulse channel noise with Marvell's proprietary ClearRF technology, while also achieving lower cost and lower power through our high integration."

"I am very impressed with the analog and digital reception performance of the Marvell hybrid demodulator in demodulating our field capture test suites covering Europe including multiple simultaneous impairments," said Keith Potter, CEO of Digital TV Labs, an independent DTV testing authority for DVB receivers in Bristol, UK.

"The demand for single chip hybrid demodulator continues to grow as people are always looking for better viewing experiences," said Paul O'Donovan, Principal Analyst for Gartner's Technology and Service Provider Research group. "The European market for integrated television sets in the home are expected to grow from approximately 10 percent to 42 percent of the total worldwide demand over the next five years, confirming Europe's commitment to digital broadcasting."
