Here are the key details about this IC:The CS8422-CNZ is found in high-performance Consumer, Professional, and Automotive audio equipment:
Why it is used in a TV
In a television, the CS8422 performs three main roles:
It can take audio from different digital sources (like the TV's internal smart system vs. an external optical input) and switch between them seamlessly.
Audio Sync (Sample Rate Conversion):
TVs often need to match the audio sample rate to the video frame rate to prevent "lip-sync" issues. The CS8422 converts various incoming sample rates (like 44.1 kHz from a music app) to the TV's standard 48 kHz internal rate.
It is frequently used to manage the signal that sends audio from your TV to an external soundbar or home theater system.
What it is: It is a 24-bit, high-performance, stereo asynchronous sample-rate converter (ASRC) with an integrated digital audio interface receiver.
Function: It supports AES3 and S/PDIF interface standards, allowing it to convert audio sample rates and receive digital audio signals.
Applications: It is commonly used in consumer, professional, and automotive audio equipment, such as A/V receivers, digital mixing consoles, and effect processors.
The "CNZ" or "CNZR" suffix indicates a lead-free, commercial-grade package.
Tools used in the video: Tweezers, Spirit, Brush, Towel. 🤞
