Creonic Introduces NCR Processor IP Core for DVB-S2X/DVB-RCS2 Satellite Communication

Kaiserslautern, Germany, September 07, 2023 - Creonic GmbH, the leading provider of IP cores for communication systems, is proud to unveil its latest addition, the NCR Processor IP core. Designed to cater to the specialized needs of the satellite communication industry, this state-of-the-art IP core is set to facilitate clock synchronization and reference source solutions.

Network Clock Reference (NCR) plays a pivotal role in ensuring precise time synchronization between satellites and user terminals. The NCR Processor IP core facilitates the dissemination of master clock information from the satellite to all connected user terminals. Traditionally, NCR packets are transmitted periodically over continuous DVB-S2 or DVB-S2X links. User terminals then utilize this master clock knowledge to regulate data transmission in time-division multiple access (TDMA) systems, such as DVB-RCS or DVB-RCS2. In TDMA systems, multiple terminals share the same frequency band, necessitating a strict transmission schedule.

Creonic's NCR Processor IP core is equipped with two key functionalities:

  1. The NCR tracker within the IP core provides a local NCR clock, which is frequency- and phase-latched to incoming DVB-S2/DVB-S2X streams containing NCR information.

  2. The NCR local clock offers a precisely settable NCR source clock, provided a stable 27 MHz clock and a precise 1 PPS (Pulse Per Second) source are available.

Its AXI4-Lite interface allows for simplier configuration and retrieval of status information. Moreover, the NCR Processor IP core seamlessly integrates with other Creonic components, including the DVB-S2X Modulator and Demodulator, DVB-S2X Decoder and DVB-RCS2 Modulator, making it a versatile choice for satellite communication systems.

With comprehensive deliverables such as HDL simulation models, VHDL testbench, C++ firmware, and extensive documentation, Creonic ensures a seamless integration experience for its customers.
