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.

1. INITIAL SETUP
1.1 Kit Contents
The CDB5378 evaluation kit includes:
• CDB5378 Evaluation Board
• USB Cable (A to B)
• Software Download Information Card
The following are required to operate CDB5378, and are not included:
• Bipolar Power Supply with Banana Jack Outputs (+/-12 V @ 100 mA)
• Banana Jack Cables (4x)
• PC Running Windows 2000 or XP with an Available USB Port
• Internet Access to Download the Evaluation Software
1.2 Hardware Setup
To set up the CDB5378 evaluation board:
• Set all jumpers and DIP switches to their default settings (see next sections).
• With power off, connect the CDB5378 power inputs to the power supply outputs.
VA- = -12 V
VA+ = +12 V
GND = 0 V
VD = +12 V
• Connect the USB cable between the CDB5378 USB connector and the PC USB port.
• Proceed to the Software Setup section to install the evaluation software and USB driver.

1.4 Self-testing CDB5378
Noise and distortion self-tests can be performed once hardware and software setup are complete.
First, initialize the CDB5378 evaluation system:
• Launch the evaluation software and apply power to CDB5378.
• Click ‘OK’ on the About panel to get to the Setup panel.
• On the Setup panel, select Open Target on the USB Port sub-panel.
• When connected, the Board Name and MCU code version will be displayed.
1.4.1 Noise test
Noise performance of the measurement channel can be tested as follows:
• Set the controls on the Setup panel to match the picture:
