MAX2169 multimode tuner

Maxim Integrated Products has launched the MAX2169, a multimode silicon tuner for mobile TV. This device receives signals in the FM, VHF-III, UHF, and L-band spectrums, making it suitable for multimode applications that need to receive mobile TV and audio broadcasts.

On-chip tracking filters, lowpass filters and LNAs eliminate the need for expensive external components, thus saving space and cost. The IC operates in either zero-IF (ZIF) mode for DVB-H and ISDB-T or in low-IF mode for DAB and T-DMB. Offering a compact multiband solution, the MAX2169 is designed for mobile multimedia applications such as cellphones, portable music players and USB sticks.

The MAX2169 operates from a single 2.7V supply and consumes only 130mW when receiving ISDB-T 13-segment signals. Power consumption in L-band mode is a low 110mW.

The MAX2169 is available in a small, 6mm x 6mm, 40-pin TQFN package, and is fully specified over the -40C to +85C extended temperature range. Prices start at $4 (1,000-up, FOB USA). An evaluation kit and reference designs are being developed to speed designs-contact the factory for availability.
