MaxLinear Inc. has released a new low-power hybrid digital/analog silicon tuner for the next generation of small and large screen TV applications. The MxL301 is designed for hybrid TV applications that require analog as well as digital performance. It offers low power consumption, consuming only 400mW in contrast to competing tuners that can consume up to 1.5W each.

Measuring 5mm x 5mm in a 32-pin QFN package, the MxL301RF is highly integrated, with built-in features such as a SAW filter function, LNAs, tracking and loop filters.

The device offers software configurable standards support allowing manufacturers to design one single front end for all global markets and then to configure the standards support on a per market basis. The MxL301RF supports major analog TV and DTV standards, including ATSC, DVB-T, DVB-H, ISDB-T 13-segment, DMB-T (H), NTSC, PAL and SECAM. The device also supports digital cable standards including ITU-T J.83 Annexes A and C [DVB-C] for Europe, China and India and Annex B [North American Cable], DOCSIS, and EURODOCSIS as well as digital terrestrial reception standards (DVB-T/H, ATSC, ISDB-T and DTMB).

The MxL301 is sampling now and will be available to ship in production to key customers in Q4 09.
