DC2799A, Demo Board Using LTC4332 SPI Extender Over Rugged Differential Link

说明

• DC2799A, Demonstration Circuit uses the LTC4332 to extend a SPI interface with 3 slave devices to up to 1200m (150m with a 500kHz SCK as factory configured). The DC2799A is designed to be compatible with the popular Pmod interface to allow for easy evaluation with the many master and slave devices in this ecosystem. The LTC4332 is a 2MHz SPI bus extender designed for operation in high noise industrial environments. The SPI bus is extended over two twisted pairs by ±60V fault protected differential transceivers. The LTC4332's extended 25V common mode voltage range allows it to bridge across different ground potentials
