Electrical characteristics

Figure 32. I2S slave timing diagram (Philips protocol)

1. Measurement points are done at CMOS levels: 0.3 × VDDIOx and 0.7 × VDDIOx.

2. LSB transmit/receive of the previously transmitted byte. No LSB transmit/receive is sent before the first

byte.

1. Data based on design simulation and/or characterization results, not tested in production.

2. Depends on fPCLK. For example, if fPCLK = 8 MHz, then TPCLK = 1/fPLCLK = 125 ns.
