Single-Chip RF Tuner Captures Terrestrial Digital Video Signals

The RF4000 single-chip television tuner targets digital-video broadcast terrestrial (DVB-T) applications. Developed by RF Magic, it enables terrestrial receivers throughout Europe, the Middle East, and Asia to achieve small physical sizes and deliver top-notch performance.

Based on RF Magic's proprietary AdaptiveTune technology, the chip was developed specifically for digital terrestrial television applications that comply with the international DVB-T standard. Adaptive-Tune lets designers program the tuner's key characteristics via software to optimize front-end performance for different environments.

The single chip contains all front-end functions and requires no external surface-acoustic-wave filters or amplifiers. It simplifies customers' RF system design and enables sleeker, more stylish receiver designs with a footprint one-fourth the size of comparable discrete tuners. Front-end solutions that comply with NorDig 2, a common platform standard for digital television used in the Nordic region, can be implemented with the RF4000 on two-layer surface-mount pc boards for manufacturing simplicity and cost-effectiveness.

Samples are now available. The company anticipates extending the product line for the North American ATSC standard in the near future. The RF4000 will cost less than $5.00 each in small lots.
