- | The distance limitation is one of the key disadvantages of these interfaces. System designers have traditionally extended these interfaces using repeaters or drivers with a higher drive strength at the expense of increasing the overall cost and power consumption. These solutions may be inconvenient for many applications and have other disadvantages that negate their usability. | + | The distance limitation is one of the key disadvantages of these interfaces.

The circuit shown in Figure (1) solves the problem of long distance, robust, SPI/I2C communication simply and easily without any sacrifices to circuit component count, operating speed, or software complexity. Ideal operation in high noise, harsh industrial environments require tolerance to large ground potential differences. The SPI/ I2C extenders feature robust transceivers which operate over an extended common mode range of ± 25V (for SPI communication) and ± 15V (for I2C communication) for distances up to 1200m. Each link consists of a single device at either end of the cable, capable of being powered from 3V to 5.5V, while a separate logic supply | The circuit shown in Figure (1) solves the problem of long distance, robust, SPI/I2C communication simply and easily without any sacrifices to circuit component count, operating speed, or software complexity.
