I2S - Ensures proper audio data transmission, synchronization, and integrity
- I2S (Inter-IC Sound) is a serial bus interface used for connecting digital audio devices. As a Verification IP (VIP), it ensures proper data transmission, signal integrity, timing, and protocol compliance in audio communication systems.
- This VIP verifies key elements such as word length, frame synchronization, clock behavior, and error handling, making it essential for testing I2S communication in a range of applications, including consumer electronics, automotive, and medical devices

I2S/TDM Serial Audio Interface with Asynchronous Sample Rate Conversion
- The IPB-I2S-TDM-ASRC combines an I2S/TDM configurable serial audio interface with two embedded stereo Asynchronous Sample Rate Converters (ASRCs).
- The ASRCs can provide very high quality in terms of harmonic distortion and noise, tolerance and rejection of input jitter.
-
AC97 Audio Controller
- Fixed 48kHz audio support
- Hardware variable sample rate support from 8kHz to 48kHz (up to 96kHz with Double Rate Audio enabled)
- Double Rate Audio support for Left, Right and Center channels
- 16 bit sample size support (18 and 20 bit support planned in future)
-
AC97 Controller IIP
- Compliant with AC'97 2.2 specification
- Supports AC'97 audio codec functionality
- Supports variable and fixed sample rate support
