www.DataSheet4U.com CRD5376 Multichannel Seismic Reference Design Features z General Description The CRD5376 board is a reference design for the Cirrus Logic multichannel seismic chip set. 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 measurement channels. An on-board test DAC creates precision differential analog signals for in-circuit performance testing without an external signal source. The reference design includes an 8051-type microcontroller 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 coefficient initialization and performs time domain, histogram, and FFT frequency analysis on captured data.
