I²S Electrical Validation

Use an oscilloscope for I2S electrical validation to ensure compliance with defined specifications. After an extended burn-in test, the oscilloscope confirms that the electrical characteristics of the signal meet the required standards.

I2S Electrical Validation Settings

1. General Settings: Setup the bus configuration, including I2S mode type (I2S, Left Justified, PCM, TDM), the channel settings, working voltage and the data rate of I2S.

2. Decode Settings： Setup the I2S data format. Bit order is either MSB First or LSB First. Data Bits can be set in a range of 1-32 bit(s).

3. Trigger Settings

4. Electrical Validation Parameter Settings: Frequency, Timing, Voltage limitation

This section displays 3 characteristics table, including

1. Frequency

2. Timing Parameters

3. Voltage requirements

The default values are referenced from the I2S specification rev3.0.
