I2S interface characteristics

Unless otherwise specified, the parameters given in Table 107 for the I2S interface are

derived from tests performed under the ambient temperature, fPCLKx frequency and VDD

supply voltage conditions summarized in Table 24: General operating conditions, with the

following configuration:

•

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

•

Capacitive load C = 30 pF

•

Measurement points are done at CMOS levels: 0.5VDD

•

I/O compensation cell enabled

Refer to Section 6.3.15: I/O port characteristics for more details on the input/output alternate

function characteristics (CK, SD, WS).
