I2S Interface characteristics
Unless otherwise specified, the parameters given in Table 120 for I2S are derived from tests
performed under the ambient temperature, fPCLKx frequency and VDD supply voltage
conditions summarized in Table 22: 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 6.3.18: I/O port characteristics for more details on the input/output alternate
function characteristics (CK,SD,WS).
Table 120. I2S dynamic characteristics(1)
1. Guaranteed by characterization results.
