TI Designs: TIDA-01401. High EMC immunity , RS-485 Interface Reference Design to Absolute Encoders Description Features This high EMC immunity Reference Design 5-V, Half-Duplex RS-485 Transceiver (THVD1550), demonstrates an RS-485 transceiver to use on both 50-Mbaud With 16-kV IEC-ESD and 4-kV EFT. the drive and within encoders such as EnDat , Eliminates Cost for External ESD Components BiSS , Tamagawa , and so on. EMC immunity , Design Achieves Highest immunity Within Industry particularly immunity against inverter switching noise, Against IEC 61000-4-4 Fast Electrical Transients is important for position encoder feedback systems Supports 4-Wire RS-485 Interface Standards Such within industrial drives. This Design supports a wide as EnDat and BiSS or 2-Wire Interfaces input voltage range (used as output voltage to the Standards Such as Tamagawa encoder) from 5 to 15 V (12 V nom) to meet the wide supply range of encoders.
