CompactPCI Serial System/Peripheral Mixed Signal DSP Cards

3U-160 Quad Input Quad Output RF Card

  • Xilinx Zynq UltraScale+ XCZU15 MPSoC having an integrated Quad Core 64-bit FPU ARM with an Analog Devices ADRV9026 SDR chip with four receivers plus two observation channels and four transmitters.
  • ARM runs U-boot, GNU/Linux, BLAS, and LAPACK. Interfaces include PCIe, Gigabit Ethernet, UART, USB 2, and SDHC. Typically controlled via SCPI over Ethernet.
  • Sixteen 16.3 Gbps SERDES directly connect the FPGAs to the backplane, supporting a full 9 card mesh with 32.6 Gbps duplex communication between each pair of cards in each direction.
  • GMSK radio with analog canceller control plus digital cancellation having >100 dB self interference cancellation for same frequency simultaneous transmission and reception, or >100 dB external interference cancellation for antijam.

3U-160 Dual Input Dual Output Wideband Baseband Card

  • Xilinx Zynq UltraScale+ XCZU15 MPSoC having an integrated Quad Core 64-bit FPU ARM with a dual 1.25 GSPS 14-bit ADC and two 2.5 GSPS 16-bit DACs.
  • ARM runs U-boot, GNU/Linux, BLAS, and LAPACK. Interfaces include PCIe, Gigabit Ethernet, UART, USB 2, and SDHC. Typically controlled via SCPI over Ethernet.
  • Sixteen 16.3 Gbps SERDES directly connect the FPGAs to the backplane, supporting a full 9 card mesh with 32.6 Gbps duplex communication between each pair of cards in each direction.
  • Emulates L-band fading channel propagation between up to 16 radios.

6U-160 Single Input Six Output Baseband Card

  • Quad Core 64-Bit FPU PowerPC and two Virtex-7 FPGAs with 2 high speed ADCs and 6 high speed DACs.
  • PowerPC runs U-boot, GNU/Linux, BLAS, and LAPACK. Interfaces include PCIe, Gigabit Ethernet, RS-232/RS-422, USB 2, and SDHC. Typically controlled via SCPI over Ethernet.
  • Twenty Eight 10 Gbps SERDES directly connect the FPGAs to the backplane, supporting 280 Gbps duplex communication in each direction.
  • Low Latency Baseband Filter-Equalizer includes two time interleaved 400 MSPS 14-Bit ADCs and six 2.3 GSPS 14-Bit DACs with on-board full dynamic range anti-aliasing filters and RF loopback.
  • Prototype board shows 90+ dB isolation in 20 MHz to 300 MHz passband up to 400 MHz, 60+ dB isolation up to 3 GHz can be improved by changing anti-aliasing filters or RF loopback.
  • Typical uncalibrated performance shows -50 dBc image rejection, 0.7 dB 6.7 nS peak to peak flatness. Calibrated performance is <-80 dBc image rejection, 0.1 dB 0.2 nS flatness.
  • Spurs include <-60 dBc ADC harmonics, <-60 dBc DAC SFDR, <-80 dBFS unrelated digital spurs.
