SX-3000 Modem SoC ASIC

SatixFy’s SX-3000 is an industry leading unique VSAT modem SoC ASIC. The device is a core element in providing DVB-S2X/RCS2 Software Defined Radio (SDR) with true beam hopping wide-band HTS terminals

SX-3000 Modem SDR SoC ASIC

SatixFy’s SX-3000 is a highly integrated Software Defined Radio (SDR) System on a Chip (SoC) Application Specific Integrated Circuit (ASIC). The device is purpose built to serve as a core component in VSAT modem product.

The device is designed to provide one integrated component for a complete VSAT modem. The SX-3000 is fully compliant  DVB-S2X/RCS2 mod/demo with up to 500 Msps HTS transponder throughput rate. In addition to providing a basic VSAT modem SDR functions, additional embedded CPUs (dual core MIPS) and multiple DSPs (CEVA XC-323) enable advanced features such as beam hopping and custom designed features. The device is designed to serve as a foundation of any VSAT modem system. Applications from standard satellite broadcast products to mobile satellite data terminals (IP – internet, TV broadcast) are good examples of the SX-3000’s capability.

A crucial component of the SX-3000 device use is a ready set of software routines, algorithms and development tools. SatixFy provides a basic set of functions for satellite communication. A complete software development environment enable product developers to provide additional features and extend basic VSAT modem communication capability. With additional computing resources (CPUs, DSPs and I/Os) SatixFy is partnering with developers to create new products with our VSAT modem as a foundation.

Key Features

The SX-3000 specifications cover the latest VSAT standards (DVB-S2X/RCS2). The ASIC also delivers additional programmable features designed for long term system viability ensuring future-proof products. Today’s VSAT modem designs need to stay compliant with future standards and enable future development in an ever changing communication landscape.

Consumer VSAT Modem Platform

The highly integrated SX-3000 SDR SoC ASIC, together with the required RF and peripheral electronics, yield a simple solution to manufacture an affordable compact VSAT board. SatixFy’s demonstration board fits inside an indoor or outdoor unit enclosure. The design is a proof-of-concept product with basic VSAT modem for data and broadcast consumer application.

Next Generation Consumer VSAT Modem Design

The SX-3000 SDR ASIC addresses the need for the next generation VSAT modems. The S-IDU is a basic indoor unit design demonstrating an economically viable product with up to date standards (i.e. DVB-S2X/RCS2) and features (i.e. multi-beam, beam hopping). The O-IDU is a compact outdoor proof-of-concept product specifically designed to meet consumer and low-cost market needs (i.e. broadband Internet, IoT/M2M, IP – internet).
