COM-1011 DS Spread-Spectrum Demodulator 10 Mchip/s

KEY FEATURES

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
