Creonic Offers High-throughput Single-chip DVB-S2X Satellite Modem for Zynq UltraScale+ RFSoC

Jul. 25, 2022 – 

Kaiserslautern, Germany, July 25, 2022 – The DVB-S2X standard is very popular for satellite communication. Its outstanding error correction performance allows it to achieve excellent spectral efficiency for a broad range of signal-to-noise ratios (SNRs) – from less than -8 dB up to 20 dB.

As such it has been adopted for many applications, like broadcasting and professional services where high data rates or a high level of robustness are key. Creonic, as an IP core provider, has been selling DVB-S2X IP cores for more than a decade.

Recently, we started shipping high-throughput single-chip DVB-S2X modem solutions based on the Zynq UltraScale+ RFSoC device family, exploiting its integrated DAC/ADC and DUC/DDC cores.

The system satisfies the ever-increasing customer needs for high data rates, e.g., when it comes to sending high amounts of data from nanosatellites back to earth within minutes. The transmitter can operate at 4 Gbps while the receiver handles up to 1 Gbps. It is possible to achieve even higher data rates with the Creonic Wideband DVB-S2X IP core portfolio.

One of our customers uses this architecture to transmit live video footage from space, showing the dispensing process of nanosatellites shortly after rocket launch.

System Design
Creonic provides the customer with the entire design of the FPGA fabric. Furthermore, there are Linux drivers running on ARM cores, offering plenty of control and monitoring capabilities. The customer only needs to feed the design with IPv4 packets and the IP cores handle the rest: The RFSoC device provides an RF output with the DVB-S2X waveform.

The transmit system is comprised of the following Creonic IPs:

The output of the modulator is handled by the DUC and the DAC of the RF Data Converter, allowing to have the output either in baseband or L-band.



DVB-S2X IP Cores

On the receive side, the following IPs are used:

Compared to conventional modem designs with separate ICs for ADC/DAC and DUC/DDC, customers significantly benefit from the higher level of integration due to smaller PCB footprint and reduced overall power consumption.

Next Steps

DVB-S2X multi-carrier solutions will be available shortly, allowing to demodulate more than 30 carriers in parallel.
