HCLK = AHB System Clock
THCLK = Period for HCLK
TP = Period of CSI_PIXCLK
The limitation on pixel clock rise time/fall time is not specified. It should be calculated from the
hold time and setup time based on the following assumptions:
Rising-edge latch data
max rise time allowed = (positive duty cycle - hold time)
max fall time allowed = (negative duty cycle - setup time)
In most of case, duty cycle is 50 / 50, therefore
max rise time = (period / 2 - hold time)
max fall time = (period / 2 - setup time)
For example: Given pixel clock period = 10ns, duty cycle = 50 / 50, hold time = 1ns, setup time =
1ns.
positive duty cycle = 10 / 2 = 5ns
≥ max rise time allowed = 5 - 1 = 4ns
negative duty cycle = 10 / 2 = 5ns
≥ max fall time allowed = 5 - 1 = 4ns
Falling-edge latch data
max fall time allowed = (negative duty cycle - hold time)
max rise time allowed = (positive duty cycle - setup time)

Non-Gated Clock Mode
Figure 83 shows the timing diagram when the CMOS sensor output data is configured for negative
edge and the CSI is programmed to received data on the positive edge. Figure 84 on page 100
shows the timing diagram when the CMOS sensor output data is configured for positive edge and
the CSI is programmed to received data in negative edge. The parameters for the timing diagrams
are listed in Table 44 on page 100. The formula for calculating the pixel clock rise and fall time is
