TDM/SI outputs—External clock delay
TDM/SI outputs—External clock High Impedance
TDM/SI inputs—External clock input setup time
TDM/SI inputs—External clock input hold time
Notes:
1. Output specifications are measured from the 50% level of the rising edge of CLKIN to the 50% level of the signal.
2. The symbols used for timing specifications follow the pattern of t
