DS Spread-Spectrum Demodulator 10 Mchip/s
  • A higher-performance newer-generation DSSS demodulator is now available: COM-1518
  • Direct sequence spread-spectrum demodulator
  • Variable chip rate up to 10 Mchips/s
  • Spreading codes:
    • Gold sequences (up to 223-1 chips)
    • Maximal length sequences, (max length 223-1 chips)
    • Barker codes (length 11, 13)
  • BPSK, QPSK selectable
  • Demodulation performances: within 1.5 dB from theory at threshold SNR of 5 dB
  • Sequential code search
  • 4-bit soft-quantized demodulated bits
  • Monitoring:
    • Receiver lock
    • Carrier frequency error
  • Connectorized 3”x 3” module for ease of prototyping. Standard 40 pin 2mm dual row connectors (left, right, bottom). Single 5V supply. Interfaces with 5V and 3.3V logic
