DFSDM characteristics
Unless otherwise specified, the parameters given in Table 91 for DFSDM are derived from
tests performed under the ambient temperature, fAPB2 frequency and VDD supply voltage
conditions summarized in Table 22: General operating conditions.
•
Output speed is set to OSPEEDRy[1:0] = 10
•
Capacitive load C = 30 pF
•
Measurement points are done at CMOS levels: 0.5 ₓ VDD
Refer to Section 6.3.14: I/O port characteristics for more details on the input/output alternate
function characteristics (DFSDM1_CKINy, DFSDM1_DATINy, DFSDM1_CKOUT for
DFSDM).
