Camera interface (DCMI) timing specifications

Unless otherwise specified, the parameters given in Table 101 for DCMI are derived

from tests performed under the ambient temperature, frcc_c_ck frequency and VDD

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

configuration:

•

DCMI_PIXCLK polarity: falling

•

DCMI_VSYNC and DCMI_HSYNC polarity: high

•

Data formats: 14 bits

•

Capacitive load C=30 pF

•

Measurement points are done at CMOS levels: 0.5VDD
