Typical output duty factor: 50 % measured at the CLK output pin.
For the respective frame frequency f fr , see Table 12 .
For the characteristics of V DD at a fixed temperature or of the temperature at a fixed V DD , see Figure 26 and Figure 27 .
For f clk(ext) > 4 kHz, it is recommended to use an external pull-up resistor between pin SYNC and pin V DD . The value of the resistor
should be between 100 k ? and 1 M ? .
All timing values are valid within the operating supply voltage and ambient temperature range and are referenced to V IL and V IH with an
input voltage swing of V SS to V DD .
