San Jose, Calif.IDT (Integrated Device Technology Inc.) has introduced a low-power, high-definition PC audio codec designed to help bring home-entertainment-level audio fidelity to enterprise desktop and notebook systems, while supporting mobile user capabilities such as advanced processing for voice over Internet protocol (VoIP).
The IDT 92HD71B features four stereo channels, and is compatible with the Intel high definition (HD) audio interface. The audio device provides stereo 24-bit resolution with sample rates up to 192 kHz. The dual digital SPDIF outputs enable simple integration with multi-channel consumer entertainment equipment, including audio integration with system HDMI video. The codec incorporates IDT proprietary technology to achieve digital to audio conversion signal-to-noise ratio fidelity in excess of 100dB. It also includes extensive optimizations to minimize unwanted audio artifacts, such as 'pops,' during system power up.
