Analog Devices Inc. DC2799A Demo Board for LTC4332

Analog Devices DC2799A Demo Board for LTC4332 extends an SPI interface with three slave devices up to 1200m (150m with a 500kHz SCK as factory configured). Analog Devices DC2799A Demo Board is designed to be compatible with the popular Pmod interface, allowing for easy evaluation with the many master and slave devices in an ecosystem.

The DC2799A Demo Board offers local side interfaces with the host SPI master as four different SPI slave devices. These slave devices support SPI modes (0,0) or (1,1) where (CPOL, CPHA). Three slave devices are associated with the remote side devices (SS1, SS2, SS3), and the fourth device (SSC) is used to configure the DC2799A’s LTC4332 SPI extenders. The DC2799A provides a remote side interface that implements an SPI master with three slave selects. The remote side master supports all four SPI modes and a unique mode may be associated with each slave select.
