The following table provides the TDM/SI input and output AC timing specifications.
The following figure provides the AC test load for the TDM/SI.
The following figure represents the AC timing from
generally reference the rising edge of the clock, these AC timing diagrams also apply when the falling edge
is the active edge.

This section describes the DC and AC electrical specifications for the high level data link control (HDLC),
of the MPC8306.

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 QE_CLK_IN to the 50% level of the signal.
2. The symbols used for timing specifications follow the pattern of t
Timings are measured at the pin.
