The STiD337 is a system-on-chip (SoC) for interactive satellite applications that includes an integrated DVB-S2/S2X demodulator for the satellite forward link with flexible GSE and MPEG-TS PID filtering. The compute platform is based on a dual-core ARM®Cortex®-A9 architecture with Neon™ coprocessors and multiple ST231 DSP offload processors. The return link implements an IQ streamer which streams a linked list of pre-calculated data to the integrated 10-bit DACs for IQ output to external up-converters. Accurate Network clock recovery (NCR) with precision real-time control is implemented for the most demanding applications. Multiple interfaces such as integrated Ethernet physical layer (PHY), USB, PCIe, VCXO, GPIO, SPI, I2C, and I2S are included to provide a complete low-cost satellite modem.
