Timing characteristics
Table 3.
1. See
2. Guaranteed by design.
3. Tdr is linked to the duty cycle, conditioned by the duration of the low level of DR signal.
4. See
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.
