Low Power ATSC 3.0 Mobile TV Tuner

STN61M0 is a cutting-edge ultra-low power mobile TV tuner. This new high-performance tuner targeted for mobile handhelds including smartphones, tablets, and USB dongles enables high quality TV watching by receiving over the air terrestrial digital broadcasting content and by providing a considerably low power RF solution for handheld devices. STN61M0 is the first single-chip ATSC3.0 mobile tuner to support high quality video and audio reception in a mobile environment, considering fast signal power changes and doppler effects while assuring co-existence with the current LTE reception band of 600MHz-700MHz.

The Chip can tune to channels anywhere between 90MHz to 858MHz and consume the smallest power attributed to its high level of integration and design intricacy. STN61M0 can support other terrestrial standards such as DVB-T/T2, ISDB-T and D-TMB. This tuner is software-­configurable to provide outstanding performance for each standard. With a core power supply of 1.2V/3.3V and digital IO power supply of 1.8V, typical power consumption is less than 80mW for mobile terrestrial operation.
