General Description
The CDB5376 board is used to evaluate the functionality
and performance of the Cirrus Logic multichannel seis-
mic chip set. Data sheets for the CS3301, CS3302,
CS4373A, CS5371/72, and CS5376A devices should be
consulted when using the CDB5376 evaluation board.
Screw terminals 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 evaluation board includes an 8051-type microcon-
troller with hardware SPIand USB serial interfaces.
The microcontroller communicates with the digital filter
via SPI and with the PC evaluation software via USB.
The PC software controls register and coefficient initial-
ization and performs time domain, histogram, and FFT
frequency analysis on captured data.
