The Cirrus Logic CDB5376 is an evaluation board for the Cirrus Logic multichannel seismic chip set. The board forms a four-channel seismic acquisition node with CS3301A geophone amplifiers, CS3302A hydrophone amplifiers, CS5372A dual modulators, a CS5376A quad digital filter, a CS4373A test DAC, a precision voltage reference, and a clock recovery PLL. An on-board 8051-type microcontroller provides SPI communication with the digital filter and USB communication with a PC. The PC evaluation software controls register and coefficient initialization and performs time domain, histogram, and FFT frequency analysis on captured data.
The manual covers initial setup, hardware setup, default jumper and DIP switch settings, software setup, self-testing, hardware description, analog and digital hardware, power supplies, software description, bill of materials, layer plots, and schematics. The CDB5376 evaluation kit includes the evaluation board, a USB cable (A to B), and a software download information card; a bipolar power supply, banana jack cables, a PC running Windows 2000 or XP with an available USB port, and internet access are required but not included.

The kit includes the CDB5376 Evaluation Board, a USB cable (A to B), and a Software Download Information Card.
A bipolar power supply with banana jack outputs providing +/-12 V @ 300 mA is required and is not included.
A PC running Windows 2000 or XP with an available USB port is required, along with internet access to download the evaluation software.
It creates precision differential analog signals for in-circuit performance testing without an external signal source.
