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 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.
