Figure 11. Timing diagram
The input signal is sampled on the rising edge of the clock while the digital outputs are
synchronized on the falling edge of the clock. The duty cycles on DR and CLK are the same.
The rising and falling edges of the OR pin are synchronized with the falling edge of the DR
pin.
