I2S Interface characteristics

Unless otherwise specified, the parameters given in Table 204 for I2S are derived from tests

performed under the ambient temperature, fPCLKx frequency and VDD supply voltage

conditions summarized in Table 120: General operating conditions, with the following

configuration:



Output speed is set to OSPEEDRy[1:0] = 10



Capacitive load CL = 30 pF



Measurement points are done at CMOS levels: 0.5VDD



IO Compensation cell activated.



HSLV activated when VDD ≤ 2.7 V



VOS level set to VOS1

Refer to Section 7.3.15: I/O port characteristics for more details on the input/output alternate

function characteristics (CK,SD,WS).
