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.
