Working Principle of WM8804GEDS/V

The WM8804GEDS/V is an advanced, application-specific integrated circuit (ASIC) featuring low power consumption with excellent performance for its class of digital audio interface products.The principle of the WM8804GEDS/V lies in the inclusion of specialized receivers and converters to process audio signals after they are received from the source. All signals are converted to a common digital audio format, then sent to the user interface or a consumer electronics device. The signals can be routed either internally (In the WM8804GEDS/V) or externally, depending on the user\'s requirements.The WM8804GEDS/V utilizes a patented architecture for interfacing and connecting digital audio signals to their destination. This architecture enables the device to assume the free-physical layer, providing a protected and adaptable data path for high-speed audio transmission.The WM8804GEDS/V prevents data integrity issues due to crosstalk, ESD, and other interferences by utilizing its advanced signal processing engine. This engine can reduce or eliminate unwanted noise or distortion while preserving signal quality.The chip also features several power optimization features, such as a variable clock signal to reduce power when data rate is low and dynamic power management to reduce power when the signal is no longer in use.

Conclusion

The WM8804GEDS/V is an application-specific integrated circuit (ASIC) for digital audio interface applications that is well suited for use in a range of Audio Special Purpose devices such as multimedia speakers, automotive audio systems, home theatre systems, and home automation systems. It features low power consumption, excellent performance and several advanced features such as multi-channel-capable receivers, conversion capabilities, and integrated protection from ESD and crosstalk. The chip also features power optimization features such as a variable clock signal and dynamic power management.
