常見問題解答
What is CS8420-CS?
The CS8420-CS is a digital audio interface receiver and sample rate converter designed by Cirrus Logic. It is commonly used in audio systems to receive and convert digital audio streams between various sample rates and formats, providing flexibility and compatibility with different audio sources and destinations.
How Does CS8420-CS Work?
The CS8420-CS operates by receiving digital audio data from sources such as CD players, digital audio workstations, or digital audio interfaces, and converting the data to a different sample rate or format if needed. This allows the audio data to be compatible with the sampling requirements of the target audio system, ensuring proper playback or processing.
How Many Pins does CS8420-CS have and What are the Functions of the Pinout Configuration?
The CS8420-CS is housed in a 28-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- SDIN, SCLK, LRCK: Serial data input, clock, and left/right channel clock pins.
- RESET, M0, M1: Control pins for reset and mode selection.
- SDOUT: Serial data output pin.
- MCLK: Master clock input pin for synchronization.
- XTI, XTO: Crystal input and output pins for clock generation.
- AGND, DGND: Analog and digital ground pins, respectively.
- AVDD, DVDD: Analog and digital power supply pins, respectively.
What are the Pros and Cons of CS8420-CS?
Pros:
- Flexible Sample Rate Conversion: Allows audio data to be converted between different sample rates, providing compatibility in diverse audio systems.
- High Performance: Provides high-quality audio conversion and interface capabilities for professional audio applications.
- Robust Interface: Supports various audio input and output formats, including I2S, left-justified, and right-justified formats.
- Integrated Clocking: Features integrated PLL (Phase-Locked Loop) for clock generation and synchronization.
Cons:
- Complex Configuration: Requires careful configuration of mode pins and clock settings for optimal performance in different audio systems.
- External Components: May require additional external components such as crystals and capacitors for clock generation and filtering.
Are There Any Equivalents/Alternatives to CS8420-CS for Recommendation?
- The WM8804 from Cirrus Logic is a similar digital audio receiver and sample rate converter with equivalent functionality.
- Alternatives to the CS8420-CS include the AK4118 from AKM and the DIR9001 from Texas Instruments.
