Wideband Radio Correlation

The CRS hardware supports wideband correlation configurations with 8 analog inputs per module, scalable to thousands of feeds, for applications such as:

  • N² F-Engine: with 1.5 GHz of bandwidth per input, a corner-turn with thousands of inputs, and high-speed offload to a GPU X-engine.

  • Real-time FFT beam-forming: for astronomy, radar, or RFI monitoring.

Designed For Radio Astronomy

Each CRS board provides 8 wideband analog inputs, sampled up to 5 GSPS.
Each crate of 16 CRS boards provides 128 wideband inputs and can be scaled up to an arbitrary number of crates, maintaining one-clock synchronization and timestamps.

High-speed transceivers on the CRS and within the backplane assembly enable full mesh corner-turns within the backplane, as well as direct offload through 100 Gbps to commercial switch topologies.

The system scales from the “pocket-correlator” implementations of a single board, to multi-subrack shuffles for large arrays of thousands of inputs.

Control software with open-source interface allows for rapid deployments and powerful system monitoring.
