Data sheets for the CS3301, CS3302, CS4373A, CS5371/72, and CS5376A devices should be consulted when using the CRD5376 reference design. Pin headers connect external differential geophone or hydrophone sensors to the analog inputs of the mea- surement channels. An on-board test DAC creates precision differential analog signals for in-circuit perfor- mance testing without an external signal source. The reference design includes an 8051-type microcon- troller with hardware SPI™ and USB serial interfaces. The microcontroller communicates with the digital filter via SPI and with the PC evaluation software via USB. The PC evaluation software controls register and coeffi- cient initialization and performs time domain, histogram, and FFT frequency analysis on captured data.
