Fourth-Generation Cirrus Logic Energy Exploration IC Allows for a Smaller and More Reliable Marine Streamer Solution.

Industry Benchmark for Low-Noise Performance Enables More Precise Geological Mapping of Potential Energy Sources within the Ocean Floor

AUSTIN, Texas -- With the release of the CS5374, Cirrus Logic, Inc. (Nasdaq: CRUS) has extended its technology leadership within ICs for energy exploration applications. The CS5374 integrates two programmable gain differential amplifiers and two low-noise Delta-Sigma modulators into a 48-pin QFN package, enabling smaller and more reliable marine streamers.

The CS5374, part of the fourth generation of ICs for energy exploration systems, provides excellent noise and distortion performance of 127 dB signal-to-noise rate and 118 dB THD (total harmonic distortion) - 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. 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.
