LV32 SPI Extension Module
Solutions to the challenges of SPI communication distance and maximum speed.
The Serial Peripheral Interface (SPI) is used as a means of communication between processors and peripheral devices in many applications. SPI was originally designed for short-distance communication between devices on the same board. However, with the development of various SPI devices today, there is an increasing demand for long-distance SPI communication beyond the confines of a single board. - It is a module that converts SPI signals into noise-resistant differential signals to extend communication distances. - It extends the communication data between the controller and the peripheral without altering it, only converting the physical signals. - The extension cable repurposes commercially available DisplayPort cables, making it highly versatile and cost-effective to implement. - The cable also includes a power line, so there is no need to provide a separate power source for the slave device. - In addition to the four SPI signals, one signal line can be used for interrupt requests from the slave to the master. - On the master side, the MISO signal becomes tri-state in response to the input of the CS signal, allowing it to be used in a multi-drop environment.
