FMC-RSxxx-8

This LPC FMC card has eight RS-xxx interfaces. Interface selection is made as a build option when ordering the board. Possible interfaces are: RS-422, RS-485, RS232.

Features

  1. RS422 or RS485 or RS232 input interfaces – orderable option, separate for each channel;
  2. All output interfaces are ESD protected, ESD protection built in IC;
  3. Main IC is SP339EER1-L;
  4. Total 8 channels of RSxxx interfaces routed to Samtec right angle ERF8-020-01-L-D-RA-L-TR connector;
  5. Supported VADJ levels 1.2V – 3.3V;
  6. VADJ and 3.3V required from FMC carrier;
  7. Power consumption: at 3.3V <= 20 mA, outputs not loaded, at VADJ <= 10 mA, signals not switching;
  8. Level translators for FMC usage, when PMOD used it not populated;
  9. Build option FMC connector or 8 6 pins PMOD male connectors with TTL signals;
  10. 3.3V or 5V supply and logic levels are supported, when used in PMOD.
