Dolphin Integration reveal high quality and common-mode noise-resilient audio CODEC targeting automotive infotainment application

Grenoble, France – August 8, 2014 ---- Dolphin Integration offer an audio CODEC targeting automotive infotainment applications, sCODS100-N.11-Xenon, providing optimal voice command and in-cabin phone conversation performances for best-in-class listening sound system.

A world leading automotive Original Equipment Manufacturer (OEM) has partnered with Dolphin Integration by approving the performances and configuration of this audio CODEC per automotive application requirements and by purchasing the infotainment module with this audio IP embedded inside.

Beside the automotive AEC-Q100 standard requiring high operating temperature range, the major automotive application concern is the noisy ground. In order to overcome this issue, sCODS100-N.11-Xenon embeds common-mode noise-resilient preamplifier in the ADC path and provides a unique “Common Mode Noise Tolerance Template (CMNT2)” specifying the tolerated noise beyond audio bandwidth. For further information on the common-mode management technique, please look at this technical article published by Dolphin Integration.

As a second noticeable innovation: an inter voltage-domain isolation-system enabling independent start-up and power-down of analog and logic power supplies of the CODEC, with control signal connected to SoC’s Activity Control Unit (ACU) for ensuring safe behaviour of the IP during power-on and power-off sequences.
