MULTIPLE SEQUENCES SOURCE Emona Module

Used

Features:

  • Four independent functional blocks are provided:
  • (i) two independent pseudo-noise, PN, sequence generators each with 10 switch-selectable multiple length sequences of up to 214-1 bits;
  • (ii) two independent Exclusive-OR functions with analog and digital level outputs to implement modulo-2 addition.
  • Each PN sequence generator and EX-OR pair is used to implement a Direct Sequence Spread Spectrum, DSSS, channel. Two DSSS channels, (2 channel CDMA), can be implemented per module: additional MULTIPLE SEQUENCES SOURCE modules may be used to implement larger multi-channel CDMA schemes. The sequences are stored in EPROM and an optional TIMS-Interactive program allows the user to generate a file for programming custom EPROMs. 

Specifications:

  • Number of Sequence Generators 2 independent PN sequence generators
  • CLK Input more than 1MHz, TTL-level
  • RESET Inputs positive going TTL-level pulse or front panel push button to reset the sequence
  • SEQUENCE Output TTL-level, length of up to 214-1 bits

The MULTIPLE SEQUENCES SOURCE is a module from Emona.
