WM9715CLGEFL/RV Interface - CODECs Application Field and Working Principle

The WM9715CLGEFL/RV is a type of Interface-CODEC (CODEC = Codec, Digital to Analog Convertor) designed to work with WM97xx series of digital audio controllers. It is able to process both digital and analog audio signals and can be used in a wide range of applications, including audio playback and recording, telephone applications, and video conferencing.

Features and Functionalities

The WM9715CLGEFL/RV has a wide variety of features that are designed to make it as versatile and useful as possible. It has two power pin configurations, allowing flexible power consumption levels, and is designed to be compliant with the WM97xx controllers. It also features a fully integrated power supply, allowing for low-power operation, and has several inputs, outputs, and controls to provide a wide range of functions. Additionally, it includes a stereo CODEC with a low-noise amplifier for high-quality audio performance.

Applications

The WM9715CLGEFL/RV can be used in a variety of applications, including:

• Audio playback and recording (e.g., CDs, DVDs, portable media players)
• Telephone applications
• Video conferencing
• Handheld multimedia devices
• In-car entertainment systems

Working Principle

The WM9715CLGEFL/RV is a digital-to-analog converter (DAC), which is an integrated circuit that converts digital data into an analog signal. The circuit uses pulse-code modulation (PCM) to convert the data stream into a series of voltage pulses that are proportional to the amplitude of the input signal. The output of the D/A converter is then amplified with a low-noise amplifier before being sent to the output circuits.The WM9715CLGEFL/RV also supplies several types of control signals to the WM97xx controllers, including volume control, key codes, and other commands. These control signals are converted to analog signals in order to actuate the appropriate functions.The WM9715CLGEFL/RV is designed to be compliant with the WM97xx series of digital audio controllers, and to provide good audio performance when used with such controllers. It is also designed to be used in low-power applications, making it suitable for portable and mobile devices.

Conclusion

The WM9715CLGEFL/RV is a versatile interface-CODEC that can be used in a variety of applications. It is designed to be compatible with the WM97xx series of digital audio controllers, and can be used for audio playback, recording, telephone applications, and video conferencing. The circuit includes a stereo CODEC, low-noise amplifier, and several control signals to provide a wide range of features and functionalities.
