Camera interface (DCMI) timing specifications

Unless otherwise specified, the parameters given in Table 199 for DCMI are derived from

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

summarized in Table 122: General operating conditions, with the following configuration:

•

DCMI_PIXCLK polarity: falling

•

DCMI_VSYNC and DCMI_HSYNC polarity: high

•

Data formats: 14 bits

•

Capacitive load CL=30 pF

•

Measurement points are done at CMOS levels: 0.5VDD

•

VOS level set to VOS1
