To meet today’s challenge of transmitting data to a host with as little latency as possible and to simplify the interfacing with modern MCUs, processors and FPGAs, Texas Instruments has developed multiSPI™, an interface that increases data transfer rates between ADCs and digital hosts, while decreasing the required clock frequency. MultiSPI retains compatibility with standard SPI. In multiSPI, throughput is increased buy the use of 4 data output lines and double data rate transfer (DDR), which allows data transfers on both on the rising and falling edge of the SPI clock
