2.3
2.3.1
The CS5376A quad digital filter performs filtering and decimation of four delta-sigma bit streams from the
CS5372A modulators. It also creates a delta-sigma bit stream output to create analog test signals in the
CS4373A test DAC.
The CS5376A requires several control signal inputs from the external system.
Configuration is completed through the SPI 1 port.
Data is collected through the SD port.
