Camera interface (DCMI) timing specifications
Unless otherwise specified, the parameters given in Table 114 for DCMI are derived from
tests performed under the ambient temperature, fHCLK frequency and VDD supply voltage
summarized in Table 21, with the following configuration:
•
DCMI_PIXCLK polarity: falling
•
DCMI_VSYNC and DCMI_HSYNC polarity: high
•
Data format: 14 bits
•
Output speed is set to OSPEEDRy[1:0] = 11
•
Capacitive load C = 30 pF
•
Measurement points are done at CMOS levels: 0.5 x VDD
