 (total harmonic distortion The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental. ) - delivering the high-precision performance needed for marine streamers used to detect potential sources for energy deep within the ocean floor.

"The CS5374's integration allows for the industry's smallest footprint, significantly reducing the overall size of the streamer design and improving mechanical reliability," said Tom Stein, vice president and general manager, Cirrus Logic's Energy, Exploration and Lighting division.

For 15 years, Cirrus Logic has been the leader in the development of high-performance integrated circuits for oil exploration and seismology seismology (sīzmŏl`əjē, sīs–), scientific study of earthquakes and related phenomena, including the propagation of waves and shocks on or within the earth by natural or artificially generated seismic signals. . Today, Cirrus Logic is the only semiconductor supplier that provides a complete seismic system, including front-end buffer and amplification, analog-to-digital conversion, high performance filtering and test signal generation. "Cirrus Logic continues to set the industry standard for performance and integration and remains the only open market component supplier committed to the development of complete data acquisition channel chipsets," Stein said.
