AC'97 Rev 2.3 Audio CODEC
General Description
Featuring four 16-bit two-channel DACs and a stereo 16-bit ADC, the ALC850 is an AC\'97 Rev 2.3 compatible multi-channel audio CODEC designed for PC multimedia systems. The ALC850 incorporates proprietary converter technology and fully meets performance requirements for PC99/2001 systems.
Four pairs of stereo outputs, with 5-bit volume control and multiple stereo and mono inputs, along with flexible mixing, and gain and mute functions, provide a complete integrated audio solution for PCs. The digital interface circuitry of the ALC850 operates from a low-power consumption 3.3V power supply.
Two integrated 50mW/20ohm headphone audio amplifiers provide high-quality personal audio listening. Utilizing Universal Audio Jack technology, Line-In and Mic-In can also serve as Headphone-Out with an amplifier advantage.
The ALC850 integrates an on-board dual PLL clock generator (14.318MHz and 24.576MHz), saving the cost of a 24.576MHz crystal. A PCBEEP generator is built-in and can be programmed by the BIOS to generate POST beeps without a buzzer. S/PDIF input and output functions are also supported, offering easy connection of PCs to consumer electronic products such as AC3 decoders/speakers, and mini disk devices.
The ALC850 supports host/soft audio from Intel ICHx chipsets, as well as audio controller-based VIA/SiS/ALi/AMD/nVIDIA/ATI chipsets. Bundled Windows series (98/ME/NT/2000/XP) and Linux drivers, EAX/Direct Sound 3D/I3DL2/A3D compatible sound effect utilities (supporting Karaoke, 26 types of environment sound emulation, 10-band equalizer), HRTF 3D positional audio, and Sensaura 3D (optional), providing an excellent entertainment package and game experience for PC users. In addition, the ALC850 is embedded with an impedance sensing capability to detect when a device has been connected to input or output jacks.

The AC-97 audio codec is a piece of software that interacts with audio hardware that is embedded onto a motherboard. In some cases, this hardware is also found on a dedicated PCI or PCI-Express expansion card. These cards contain the necessary digital-to-analog conversion hardware and allow physical connection of audio input and output devices. These devices include microphones, headsets, recording devices and speaker systems.
Audio expansion cards in this class typically do not contain a microprocessor for audio processing. In order to fill this need, the AC-97 software is installed onto a computer and runs in the background. There, it uses cycles on the system's CPU to perform audio operations. Although this keeps hardware costs down, it can place an extra burden on the CPU. This is especially true when 5.1, 7.1 or higher audio standards are used. Effects such as Dolby Digital, EAX and SRS WOW can increase CPU utilization substantially. Adding a sound card with an onboard microprocessor is a common means to speed up gaming computers whose processors are overburdened by these operations.
Audio chipsets that rely on the AC-97 audio codec are typically found on motherboards. They are frequently a small chip that is wired directly to the "south bridge" chipset component. In other cases, the relevant hardware is embedded into a larger integrated circuit. This hardware will often identify itself to Windows as a generic audio device. In some cases, it will identify itself as an AC-97 device. This hardware will not function properly without the AC-97 codec software.
This software is typically found on a motherboard manufacturer's website or a CD-ROM included with the motherboard or pre-built computer. In the event that this cannot be located, a generic AC-97 installation package can be used. Note, however, that specialized releases including the AC-97 codec software also include specialized control panels and utilities that unlock certain features of specialized hardware. When possible, use the audio hardware manufacturer's recommended software.
