L2SYNC_IN to data and parity input hold  
Note:  
1. All input specifications are measured from the midpoint voltage (1.4V) of the signal in question to the midpoint voltage of the rising edge of the input  
L2SYNC_IN. Input timings are measured at the pins (see Figure 7).  
2. Rise and fall times for the L2SYNC_IN input are measured from 0.4 to 2.4V.  
3. Guaranteed by design and characterization, and not tested.
