General Description
The CDB5378 board is used to evaluate the functionality
and performance of the Cirrus Logic single-channel seis-
mic chip set. Data sheets for the CS3301, CS5373A, and
CS5378 devices should be consulted when using the
CDB5378 evaluation board.
Screw terminals connect an external differential geo-
phone or hydrophone sensor to the analog inputs of the
measurement channel. 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 SPI™ and 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.
