Description

VIA Technologies' VT1616TM 20-bit audio codec conforms to the AC'97 2.2 and S/PDIF Output specifications. The VT1616 integrates Sample Rate Converters on all channels andcan be adjusted in 1Hz increments. There is a provision in hardware for down-mixing the 6 channels into stereo when only two endpoints are available. The analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D surround sound effect for stereo media. This codec is designed with aggressive power management to achieve low power consumption. When usedwith a 3.3V analog supply, power consumption is further reduced. The primary applications for this part are desktop and portable personal computers multimedia subsystems. However, it is suitable for any system requiring 6-channel audio output for home theater systems at competitive prices.
