CPH6340 P-Channel Silicon MOSFET

The CS4328 is a complete stereo digital-to-analog output system. In addition to the traditional D/A function, the CS4328 includes an 8 digital interpolation filter followed by a 64 oversampled delta-sigma modulator. The modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows for infinite adjustment of sample rate between 1 kHz and 50 kHz while maintaining linear phase response simply by changing the master clock frequency. The CS4328 also includes an extremely flexible serial port utilizing two select pins to support four different interface modes. The master clock can be either 256 or 384 times the input word rate, supporting various audio environments. By Cirrus Logic, Inc.

The CS4328 serves as an advanced stereo digital-to-analog converter (DAC) designed to deliver high-fidelity audio outputs. It integrates multiple components essential for converting digital signals into analog waveforms, making it suitable for various audio applications. The core of the CS4328's functionality lies in its digital interpolation filter, which enhances the input signal by interpolating between existing data points, resulting in a more refined output.

Following the interpolation filter, the CS4328 employs a 64 oversampled delta-sigma modulator. This modulator plays a crucial role in noise shaping and oversampling, allowing for high-resolution audio playback. The output of the modulator is directly linked to an analog low-pass filter, which is characterized as ultra-linear. This filter is responsible for smoothing the output signal, effectively removing high-frequency noise components and ensuring a clean analog output.

One of the standout features of the CS4328 is its ability to adjust the sample rate infinitely within a range of 1 kHz to 50 kHz. This flexibility is achieved by modifying the master clock frequency, which can be set to either 256 or 384 times the input word rate. This capability enables the device to cater to various audio environments, ensuring compatibility with different sampling rates and formats.

Additionally, the CS4328 incorporates a highly adaptable serial port that utilizes two select pins. This design allows the DAC to support four distinct interface modes, enhancing its versatility in integration with various digital audio systems. The combination of these features makes the CS4328 a robust solution for high-quality audio conversion, suitable for both consumer and professional audio applications.The CS4328 is a complete stereo digital-to-analog out- put system.
