Creonic Provides Excessive-throughput Single-chip DVB-S2X Satellite tv for pc Modem for Zynq UltraScale+ RFSoC


Kaiserslautern, Germany, July 25, 2022 – The DVB-S2X commonplace could be very in style for satellite tv for pc communication. Its excellent error correction efficiency permits it to attain wonderful spectral effectivity for a broad vary of signal-to-noise ratios (SNRs) – from lower than -8 dB as much as 20 dB.

As such it has been adopted for a lot of purposes, like broadcasting {and professional} providers the place excessive information charges or a excessive degree of robustness are key. Creonic, as an IP core supplier, has been promoting DVB-S2X IP cores for greater than a decade.

Not too long ago, we began transport high-throughput single-chip DVB-S2X modem options primarily based on the Zynq UltraScale+ RFSoC gadget household, exploiting its built-in DAC/ADC and DUC/DDC cores.

The system satisfies the ever-increasing buyer wants for prime information charges, e.g., in the case of sending excessive quantities of information from nanosatellites again to earth inside minutes. The transmitter can function at 4 Gbps whereas the receiver handles as much as 1 Gbps. It’s doable to attain even larger information charges with the Creonic Wideband DVB-S2X IP core portfolio.

Considered one of our prospects makes use of this structure to transmit reside video footage from area, exhibiting the dishing out strategy of nanosatellites shortly after rocket launch.

System Design
Creonic offers the client with your entire design of the FPGA cloth. Moreover, there are Linux drivers operating on ARM cores, providing loads of management and monitoring capabilities. The client solely must feed the design with IPv4 packets and the IP cores deal with the remaining: The RFSoC gadget offers an RF output with the DVB-S2X waveform.

The transmit system is comprised of the next Creonic IPs:

  • DVB-GSE Encapsulator, performing generic stream encapsulation, i.e., changing IP packets into baseband frames, as anticipated by DVB-S2X.
  • DVB-S2X Modulator, producing samples of the DVB-S2X waveform within the baseband. It’s versatile in lots of features reminiscent of image charges, roll-off elements, code charges, and block sizes.

The output of the modulator is dealt with by the DUC and the DAC of the RF Knowledge Converter, permitting to have the output both in baseband or L-band.

On the obtain facet, the next IPs are used:

  • DVB-S2X Demodulator, taking samples within the baseband after processing with the ADC and DDC cores. The demodulator is versatile similar to the modulator. It presents non-compulsory assist for the very-low SNR (VLSNR) characteristic of the usual and offers absolutely synchronized advanced symbols on the output.
  • DVB-S2X LDPC and BCH decoder, performing deinterleaving and ahead error correction on the demodulator output.
  • DVB-GSE Decapsulator, assembling the initially despatched IP packets from the DVB-S2X baseband frames.

In comparison with standard modem designs with separate ICs for ADC/DAC and DUC/DDC, prospects considerably profit from the upper degree of integration as a consequence of smaller PCB footprint and diminished general energy consumption.

Subsequent Steps

DVB-S2X multi-carrier options will likely be accessible shortly, permitting to demodulate greater than 30 carriers in parallel.
