The W681360WG is an integrated 6-channel frame-synchronous audio inter-chip interface compliant with the Intel AC\'97 version 2.1 specification. It is the ideal solution for applications that require an AC-link audio inter-chip bridge for multi-channel audio applications. This chip is able to provide a high-speed, loss-less audio data interface between different audio/video codecs such as the Intel HD Audio Codec, Realtek ALC888 and VIA Envy HD Audio codec.

The W681360WG is capable of providing full bi-directional ISOTP (Inter-System Transport Protocol) transfer of 32 kHz to 192 kHz audio stream data, with sample rates of up to 48 kHz (32 kHz, 44.1 kHz, 48 kHz). The W681360WG can be combined with an audio controller to provide an audio interface based on the PCI bus, eliminating the need for an ISA bus. The chip is also capable of providing multiple streams of play and record audio, through the use of the AC-link AUDPCM (Audio Data Protocols Command) feature. The W681360WG supports full synchronization capabilities, allowing different audio codecs to be synchronized when performing audio processing and playback functions.

The W681360WG is designed with an integrated dual-channel ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter), as well as an integrated functional controller for audio stream format conversion. The ADC/DAC features 16-bit resolution and can be used for multi-channel audio data conversion. The W681360WG also features an integrated headphone amplifier and an independent dual-channel speaker amplifier. The headphone amplifier is also able to provide independent audio output to two headphones, while the independent dual channel speaker amplifier can support up to 4 pairs of speakers.

The W681360WG interfaces with audio controllers and AC-link codecs through a 32-bit AC-Link Data bus. This bus can provide up to sixteen audio streams for either playback or recording. The W681360WG also includes an I2S (Inter-IC Sound) interface, which is used to provide digital audio data to and from the AC-link codec. The W681360WG also supports the industry-standard SPDIF (Serial Digital Input/Output Format) interface, providing 8-channel digital audio output.

The W681360WG provides an integrated solution for applications needing a high-performance, low-power AC-link audio interface. With its integrated hardware and software, the W681360WG is able to provide an optimized solution for the most demanding audio applications. The W681360WG is ideal for applications requiring a full featured, fully compliant AC-link interface, as well as multi-channel audio input/output, and full AC-link audio trans-coding.
