TDM Timing
Figure 18 shows the TDM input AC timing.
Note:
For some TDM modes, receive data and receive sync are input on other pins. This timing is also valid for them. See
the MSC8144E Reference Manual.
Figure 19 shows TDMxTSYN AC timing in TSO=0 mode.
Figure 20 shows the TDM Output AC timing

Notes:
1.
Values are based on a a maximum frequency of 62.5 MHz. The TDM interface supports any frequency below 62.5 MHz.
2.
Values are based on 20 pF capacitive load.
3.
Values are based on 10 pF capacitive load.
4.
The expression is for common calculations only.
