Digital filter for sigma-delta modulators (DFSDM) characteristics

Unless otherwise specified, the parameters given in Table 90 for DFSDM are derived from

tests performed under the ambient temperature, fpclkx frequency and VDD supply voltage

summarized in Table 13: 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: 0.5×VDD

Refer to Section 6.3.17: I/O port characteristics for more details on the input/output alternate

function characteristics (DFSDMx_CKINx, DFSDMx_DATINx, DFSDMx_CKOUT for

DFSDMx).
