DVB-T Mobile Digital TV Receiver Module - Abilis

Abilis announced the availability of the AS-102, a DVB-T mobile digital TV receiver chip/module. The new device integrates multi-band RF tuner, demodulator, memory, and USB 2.0 interface onto a single chip, requires no active RF components, and consume very low power (below 350mW) - suitable for battery operated portable devices. The TV receiver SoC enables rapid design of compact and low cost mobile digital TV (MDTV) solutions for many applications including PCs (Personal Computers), PNDs (personal navigation devices), set-top boxes, PMPs (personal multimedia players).

Application Example of AS-102 DVB-T Mobile Digital TV Receiver Chip

The AS-102 TV receiver chip is a cost optimized derivative of the multi-standard AS-101 chip for DVB-T only applications. It provides a complete, multi band solution, from the antenna to the MPEG transport stream data. Various physical interfaces are provided, including USB for PC centric applications and TS for STB or IDTV applications.

• PCs, laptops, PDAs
• PC add-on cards
• USB Sticks
• SDIO cards
• Handheld TV sets
• Portable Media Players
• IDTV
• Set Top Boxes

About Abilis
Abilis Systems, a Kudelski Group company, is a fabless semiconductor company, founded in 2004 by a team of former Motorola SPS employees. Abilis develops single chip CMOS solutions for OFDM-based radio communication standards, including mobile TV receivers and high speed internet access transceivers. In 2005, Abilis Systems became part of the Kudelski Group and actively cooperates with the Group's DTV company Nagravision to propose more secure and fully featured conditional access solutions to mobile TV operators.

About the Kudelski Group
The Kudelski Group (SWX: KUD.VX), is the world leader in digital security. Its technologies are used in a wide range of applications requiring access control and rights management, whether for securing transfer of information (digital television, broadband Internet, video-on-demand, interactive applications, etc.) or to control and manage access of people or vehicles to sites and events. The Kudelski Group is headquartered in Cheseaux-sur-Lausanne, Switzerland.

Combining all functions onto a single die, rather than the "System in Package" (SiP) approach of mounting multiple dies and passive components into a single chip (package/module), significantly reduces the overall cost and size of the component (9mm*9mm). Package: QFN
