產品詳情

SaTurn is a state-of-the-art of professional DVB-S and DVB-S2 demodulator. The board is a high performance demodulator for advanced DVB satellite reception. It supports up to 240Mbit/s and operates in 16APSK and 32APSK with a very low implementation loss as well as the DVB-S2X roll off.


SaTurn board is a compact and powerful OEM unit, especially designed and developed for fast integration, addressing the satellite market. SaTurn integrates the complete technology core required to perform high quality demodulation based on a high level knowledge. SaTurn demodulator can be used either with LNB satellite blocks or with L-band (from 950 MHz to 2150 MHz) receivers. In the most robust MODCOD, the C/N can go below 0 dB and SaTurn module synchronises and demodulates correctly the input signal with automatic MODCOD detection.


SaTurn is a DVB-S2 demodulator supporting multi-stream (as defined in EN 302 307) and proposes to deliver up to 2 simultaneous Input Stream Identifier (ISI), corresponding to up to 2 MPTS contents (Multiple Program Transport Streams). Thanks to the ACM feature,SaTurn allows the MODCOD seamless switching, change the robustness of the transmission and keep your Quality of Service.


Depending on your integration, to facilitate your time to market and to have a better efficiency, SaTurn offers the possibility to use standard ASI outputs or a dedicated connector. SaTurn offers a flexibility to improve your integration requirements.


Customers can control this module by using a very simple API protocol thanks to both ports I2C and/or Serial. Moreover, full control and error monitoring facilities are available and signal statistics (C/N, FER, PER) are provided.


An evaluation kit is available to discover all SaTurn possibilities & performances and make a quick integration. SaTurn Starter Kit is a complete development board solution giving customers instant access to the capabilities of SaTurn. The Starter Kit is either available as an aluminium box or as 1U Rack unit.
