Overview

• Direct-Sequence Spread-Spectrum (DSSS) burst-mode digital modulator/demodulator
• Burst mode operation:
• Fixed-length 512-bit data frames from/to LAN/UDP ports
• Multiple frames transmitted efficiently with only 32-symbol separation
• Acquisition: 1600-symbol preamble with no apriori knowledge of arrival time
• Large frequency acquisition range: ±(chip_rate / 64) or (1.8*symbol_rate), whichever is smaller, with no apriori knowedge
• End-to-end latency: 2672 symbol / modulation symbol rate. For example 1.2ms at 2.5Msymbols/s
• Programmable chip rate, up to 79.5 Mchips/s
• 2047-chip Gold codes
• Data rate practical range from chip_rate/2047 to chip_rate/30
• Built-in tools: PRBS-11 pseudo-random test sequence, BER tester, AWGN generator, internal loopback mode
• Monitoring: Carrier frequency error, SNR, BER
• Interface compatibility:
• COM-3010 [925 - 2175MHz] receiver
• COM-3011 [20MHz - 3GHz] receiver
• COM-3007 [2.3 - 2.8GHz] & [1.15 - 1.4GHz] receiver
• COM-3504 dual ADCs/DACs
• COM-4009 Digital to [400MHz - 4.4GHz] RF modulator
• COM-2001 Dual digital-to-analog conversion
