TDM/SI
The following figure provides the AC test load for the TDM/SI.
The below figure represents the AC timing from
edge of the clock, these AC timing diagrams also apply when the falling edge is the active edge. The following figure shows the
TDM/SI timing with external clock.

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. Timings are
2. The symbols used for timing specifications follow the pattern t
measured at the pin.
