Electrical Characteristics
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 cyclehold time)
max fall time allowed = (negative duty cyclesetup time)
In most of case, duty cycle is 50/50, therefore:
max rise time = (period/2hold time)
max fall time = (period/2setup time)
For example: Given pixel clock period = 10 ns, duty cycle = 50/50, hold time = 1 ns, setup time = 1 ns.
positive duty cycle = 10/2 = 5 ns
max rise time allowed = 5 –1 = 4 ns
negative duty cycle = 10/2 = 5 ns
max fall time allowed = 5 –1 = 4 ns
Falling-edge latch data:
max fall time allowed = (negative duty cyclehold time)
max rise time allowed = (positive duty cyclesetup time)

Non-Gated Clock Mode Timing
In non-gated mode only, the VSYNC, and PIXCLK signals are used; the HSYNC signal is ignored. Figure
3 and Figure 4 show the different clock edge timing of CSI and Sensor in Non-Gated Mode. Table 3 is the
parameter value. Figure 11 and Figure 12 show the non-gated clock mode timings of CSI, and Table 22
lists the timing parameters.
