Description

The TIDA-00557 reference design provides an interface for a true RS-232 (eight signal + ground) physical layer interface for data terminal equipment (DTE) using a DB-9 plug-type connector with a provision for a data communication equipment (DCE) interface. This is intended for smart grid IED’s, protection relays and substation automation segments. This design meets +-/ 8kV contact discharge ESD protection as per IEC61000-4-2 and +/-1kV surge protection as per IEC61000-4-5.

Features
  • Demonstrated Modem Control Hardware using RS232 with 2,4 and 8- wire interface
  • Provide DTE /DCE Interface with  DB-9 connector
  • Baud Rate 1200, 2400, 4800, 9600, 19200-115200bps
  • SN6501 transformer driver  based Isolated output
  • Galvanic Isolation by Digital isolators with options of 2, 4 and 8 Wire interface
  • Operates with Single 5V input
  • ESD IEC61000-4-2 +/- 8kV Contact Discharge
  • Surge IEC61000-4-5 +/- 1.0kV
