Figure 9. TDM Signal Diagram

Note:

Output specifications are measured from the 1.4V level of the rising edge of CLKIN to the

TTL level (0.8 or 2.0V) of the signal. Timing is measured at the pin.

Note:

Input specifications are measured from the TTL level (0.8 or 2.0V) of the signal to the 1.4

level of the rising edge of CLKIN. Timing is measured at the pin.
