Analog Devices LTC4331 | Demoboard EVAL-CN0564 - ARDZ
Robust SPI/I2C Communications for Industrial Applications
Details
| Topologie | Sonstige Topologie |
Beschreibung
The LTC4331 is a point-to-point SMBus compatible I2C slave device extender designed for operation in high noise industrial environments. Using a ±60V fault protected differential transceiver, the LTC4331 can extend an I2C/SMBus bus, including SMBALERT and a control signal, over a single twisted pair differential link up to 1200m. With an extended common mode operating range the solution provides tolerance to large ground differences between nodes. For EMI sensitive environments, a slew rate control pin reduces the EMI emitted from the differential link.In addition, the LTC4331 can act as an I2C to I2C bridge allowing independent bus frequencies between the local and remote networks. The solution is completely transparent to the master requiring no additional code in most cases; however, a control interface is provided for additional configuration and fault monitoring.A master controller fully supporting SCL clock-stretching is strongly recommended.
