INPUT / OUTPUT CLOCK TIMING
The inputs and outputs are aligned ideally. But due to the circuit delays, there is delay between the inputs and outputs.

1. Typical delay provided as reference only.
2. ‘Peak to Peak Delay Variation’ is the delay variation that is guaranteed not to be exceeded for IN11 in Master/Slave operation.
3. Tested when IN11 is selected.
