Analog mobile TV receiver chip integrates internal antenna
June 09, 2011 // Julien Happich
Telegent Systems introduced its fifth generation TLG12xx family of analog mobile TV receivers along with what it claims to be the industry's first integrated internal antenna and entertainment services platform. Telegent’s internal antenna design offers a more aesthetically pleasing and reliable solution to handset brands and consumers and eliminates the risk of returns caused by antenna breakage, interference or user handling error.
The solution delivers equivalent or better reception quality than a whip antenna in both UHF and VHF bands through integration with on-chip circuitry for automated sensitivity optimization. The reference design enables printed circuit board manufactures to support both internal and whip antenna options with a common board. The TLG12xx series integrates DC-DC power management, lowering system power by more than 50% relative to competitor solutions.
With a footprint less than 1cm2, it is up to 60% smaller and its external bill of materials is more than 70% lower than competing solutions, claims the manufacturer. In addition, the TLG12xx incorporates new video algorithms that reduce streaking and trailing often associated with fast motion images such as sporting events. The system includes a bundled TV player that speeds manufacturer time to market and improves user experience with features such as automatic video standard detection, enabling 1-click broadcast channel scan. The solution supports both ITU601 and EMI interfaces. The TLG12xx series is sampling in a 5x5mm package (TLG1210), 6x6 mm package (TLG1223) that is pin-to-pin compatible with previous and future TV receivers in Telegent’s product portfolio, and a 7x7mm package (TLG1211) optimized for low-cost basebands without ITU601 support.
