The TV experience is evolving in many parts of the world and customers are asking for increased levels of concurrent channel reception to support multi-device TV watching having on-demand IP TV as well as having multi-channel recording capability. SiTune’s Total Spectrum Reception (TSR™ ) family of Integrated Circuits represents a unique forward-looking architecture allowing customers to receive up to eight channels of video, high speed Internet, and VoIP from their cable providers and up to eight channels of video from satellite providers all from one single chip in the same box. TSR™ has the ability to simultaneously receive up to 155 channels due to its unsurpassed level of integration that includes a very high performance RF front-end, a multi-GS/s high resolution Analog-to-Digital Convertor, a complex Digital Signal Processing Unit, and all Demodulators/Framers needed for cable and/or satellite reception.
SiTune’s TSR™ family is a technology driver enabling a wide range of future products powering next generation cable and satellite gateways and stackers.

TSR™ Satellite


SiTune’s family of Giga-Bandwidth TSR™ satellite products are innovative designs that acquire the entire satellite spectrum and digitize and demodulate up to 8 DVB S/S2 signals. SiTune’s TSR™ has unique and patented architecture that reduces size and delivers outstanding performance while consuming only 1.6 watts of power. Utilizing cost-effective technology to deliver exceptional DVB S/S2 signal reception at only 200mW/channel makes SiTune’s TSR™ family of satellite products ideally suited for multi-receiver applications.

In parts of the world, broadcasting through terrestrial towers or satellites is the primary methodology for transmitting TV signals. SiTune distinctively supports the TV and Set Top Box markets of these regions by offering an innovative concurrent satellite/terrestrial tuner. SiTune’s concurrent tuner is the “ultimate radio” because its unique multi-tuner integration places terrestrial and satellite tuners on one die effectively cutting cost by 50%, while its novel design to solve hard interference problems leads the way to an unrivaled multi-channel experience.

SiTune concurrent tuners represent a family of unique, high-performance satellite/terrestrial radios. They are capable of simultaneously receiving up to 6 channels of terrestrial and satellite channels and by providing two tuners on one die, they significantly reduce BOM cost and TV module sizes by at least 50%.


Being first in its class, SiTune’s family of 1T/1S products are highly integrated ICs that incorporate one satellite tuner and one terrestrial/cable tuner on the same die. SiTune’s 1T/1S products support ALL TV STANDARDS with the satellite tuner supporting DVB-S/S2, ISDB-S, and ABS-S. Each device’s terrestrial/cable tuner covers the 50MHz to 1GHz band, while the satellite tuner covers the 950MHz to 2150/3250MHz range. 1T/1S devices have one LOW-IF output for the terrestrial/cable tuner and one zero-IF output for the satellite tuner. Two channels working together use only 650mW of power, which represents a considerable advantage to system designers coping with PCB power dissipation. SiTune’s LOW POWER RF CMOS technology is the key to all of this innovation.

Devices are evolving with an ever-increasing ability to communicate directly with the World Wide Web and with one another. Applications such as home automation, healthcare, emergency response, intelligent shopping, and smart product management are or will be endowed with sensors, actuators, and transceivers and have the ability to make decisions based on information those devices receive from other devices. All the “things” we deal with on a daily basis will connect together to further enable an easier, more productive life. Such applications will require schemes that enable MANY devices to connect to networks in a reliable efficient way, however, when numerous and various devices attempt to access common wireless channels, increasing contention and access delay will be a challenge as the number of devices goes up. As more devices attempt to access the same wireless band, the greater the amount of contention, which in turn may result in higher connection failure rates. This scenario worsens especially when devices use popular wireless bands such as the 2.4 GHz of Industrial, Scientific and Medical Radio Bands shared by many standards such as IEEE 802.15.4 and IEEE 802.11. Consequently, a need exists to optimize the management of this popular but congested spectrum more effectively in order to maximize channel distribution among an increasing number of devices while also finding ways to reduce contention issues.
Our patent pending IoT solution offers an effective answer to contention issues due to its many key features:

  • Cutting-Edge: Our solution utilizes SiTune’s latest radio technology which achieves unprecedented performance and functionality in capturing wireless signals over a shared wireless spectrum. Alongside patent pending access algorithms, our solution attacks contention issues through a novel cutting-edge approach.
  • More Connections: By allowing more devices to connect concurrently, our solution makes it possible to build larger networks with a greater number of nodes while simultaneously achieving reduced access delays and higher network performance.
  • Compact: With our patented level of integration and wireless radio sophistication, the end product is compact and efficient.
  • Inexpensive: The end product attains a supreme level of integration, resulting in a highly cost-effective solution due to significantly reduced BOM requirements..
