Overview

The STN61M0 is a highly integrated low-power single-chip tuner capable of receiving terrestrial television UHF frequency bands and meets specifications of digital television standards for terrestrial mobile TV applications. 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 100mW for mobile terrestrial operation.

The STN61M0 covers all functions in a receiver chain, from the RF input to the baseband outputs and is designed for low noise, high linearity, and very low power consumption required in mobile TV applications in smart phones, tablets, notebooks and USB dongles. Internal AGC loops are designed to handle high-­power signals, adjacent channels, and interference while preserving SNR and linearity performance. The RF AGC is handled internally, while a demodulator controls part of the IF AGC. The STN61M0 tuner performs across the entire frequency and power range with a differential input from an antenna. 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 100mW for mobile terrestrial
