GTX0051 - Adaptive Noise Canceling Microphone Processor

Audio Demonstration

Adaptive Noise Canceling Microphone Processors
GTX0051/53/60 Series

Dynamically Adapt Microphone Pattern to Track and Cancel Interference Noise.

  • Up to 20dB peak noise rejection of stationary and non-stationary noise sources with active directional pattern
  • Wind Noise Protection automatically reduces wind noise by 20dB
  • Natural voice quality through Analog signal processing - voice is not distorted, with no artifacts or latency as introduced by DSP solutions
  • Dual Microphone Technology improves voice clarity in all environments
  • Flat frequency response from active microphone array
  • Extremely low power (200uA) - No external battery required for wired headsets

Listen to an audio demonstration of Noise cancellation, Wind Performance, and Natural Voice Recovery. The performance of a GTX0051/53/ 60 series part is demonstrated in a noisy restaurant environment as well as standard text speech, to demonstrate performance for noise canceling, wind detection and natural sounding voice recovery as compared to DSP based noise canceling processors. The Analog processing of GTX series parts, introduce zero artifacts and latency and exhibit a distinct advantage over DSP based solutions for clarity and noise cancellation, both in Blue Tooth and Wired headset environments.

GTX0100 - Active Noise Canceling Processor with Integrated Custom Tuned Filters

Active Noise Canceling Processors with Integrated Custom Tuned Filters
GTX0100/0150 Series

Single IC with 20dB Active Noise Canceling over Wide Frequency range in single chip solution for Over-ear, On-ear, and Ear-bud applications.

  • Up to 25dB Noise Canceling @ 200Hz
  • Wide Noise Cancel frequency range from 40Hz - 800Hz
  • Full range thru audio frequency response from 20Hz to 20kHz
  • Programmable, on chip, filters optimize Noise Cancellation profile
  • Highly integrated single IC which lowers BOM cost by up to 66% and BOM area from 50%-80% over discrete solutions

GTronix' Development and Production Kits

For both Feed-back and Feed-forward Headphone designs, provide the on chip, tuned IC filters with customer designed Noise Cancel profiles.

  • Tunable, on chip, filters are used to optimize different headphone designs from the same design platform, thus enabling faster time to market with GTronix IC's
  • Customer noise cancel profiles are available to be programmed over a broad range of Headphone transfer functions
  • Automated, customer controlled noise cancel calibration will correct for variation in headphone, microphone, speaker and other components, improving performance and enhancing yield without requiring manual adjustments
  • Increased production yield and lower cost by automatic calibration via GTronix' PC based program is a significant improvement in cost and repeatability of final headset specifications vs. manual adjustments presently done at end of headphone assembly
