AK4120VF

Audio Special Purpose

AK4120VF is a digital interface receiver designed specifically for audio applications, integrating various functions such as serial audio data receiving, data format conversion, and detection of sampling rate. It is highly suitable for high-grade audio applications such as portable music players and home entertainment, providing excellent sound quality and reliability. This article will discuss the application fields and working principles of the AK4120VF.

Application Fields

The AK4120VF digital interface receiver establishes a digital signal connection and receives audio signals by using a coaxial cable and various kinds of digital signal source, such as CD changers, portable audio players, personal media players, audio streaming and recording systems. It can be used in such audio sources as DVD recorder, HDTV, and home cinema to support full digital connection. What\'s unique about the AK4120VF is that it allows both the audio signal and the power supply from the digital signal source.

In addition, the AK4120VF also provides an analog signal input that can be connected to an external amplifier for increased quality. Furthermore, due to its wide bandwidth, it can support sampling rates up to 192kHz, thus bridging the gap between the digital and the analog world. As a result, it is suitable for use in high-end digital audio systems, such as car audio and home audio systems.

Working Principle

The AK4120VF digital interface receiver is composed of a transformer circuit, an analog receiver, a signal-to-noise ratio (SNR) detection circuit and a digital signal processing (DSP) block. The transformer circuit isolates the electrical connection between the digital signal source device and the interface, while the analog receiver detects the digital signal and converts it into an analog signal. The SNR detection circuit is used to detect the signal strength and noise level of the incoming signal, while the DSP block is used to process the analog signal and convert it into a digital representation of the signal.

Once converted into a digital signal, the AK4120VF is able to detect the sampling rate of the signal, enabling it to automatically adjust the sampling rate of the device to match that of the incoming signal. This allow for seamless and optimal audio performance. Furthermore, the AK4120VF also supports data format conversion, allowing for compatibility with standard audio data formats such as CD, MP3 and WAV.

The AK4120VF is an innovative device that is designed to provide excellent quality audio performance for audio applications. It is capable of providing a digital signal connection as well as data format conversion, making it suitable for use in a variety of audio applications. In addition, its wide bandwidth makes it capable of supporting a wide range of sampling rates, thus making it suitable for use in high-end audio systems. As such, the AK4120VF is an ideal choice for providing high-quality audio transmission in a range of applications.
