The CDB5374 is a Cirrus Logic evaluation board used to evaluate the functionality and performance of the multichannel marine seismic chip set. The board is built around a four-channel seismic acquisition node containing the CS5374 dual amplifier and delta-sigma modulator, the CS5376A quad digital filter, a test DAC and a precision voltage reference, with an on-board 8051-type microcontroller that talks to the digital filter over SPI and to a PC over USB.
The manual (document DS862DB1, January 2009) covers initial setup, kit contents, default jumper and DIP switch settings, software and USB driver installation, and self-testing with noise and distortion tests. It then describes the analog and digital hardware, power supplies and PCB layout, explains the PC evaluation software panels, and closes with the bill of materials, layer plots and schematics.
| Acquisition node | Four-channel seismic acquisition node |
|---|---|
| Digital filter | CS5376A quad digital filter (1x) |
| PC communication | USB communication with PC |
| Required power supply | Bipolar power supply, +/-12 V @ 300 mA (not included) |
| PC operating system | Windows 2000 or XP with an available USB port |
| PC software analysis | Time domain, histogram and FFT frequency analysis |
The kit includes the CDB5374 evaluation board, a USB cable (A to B) and a software download information card.
A bipolar power supply with banana jack outputs (+/-12 V @ 300 mA) and four banana jack cables, which are not included in the kit.
The software performs time domain, histogram and FFT frequency analysis on captured data, and handles register setup and control.
A PC running Windows 2000 or XP with an available USB port is required.
