Figure 19 shows the TDM input AC timing.
Note: For some TDM modes receive data and receive sync are being input on other pins. This timing is valid for them as well.
See the MSC8144 Reference Manual.
Figure 20 shows TDMxTSYN AC timing in TSO=0 mode.
Figure 21 shows the TDM Output AC timing

TDM Timing
Values are based on a a maximum frequency of 62.5 MHz. The TDM interface supports any frequency below 62.5 MHz.
Values are based on 20 pF capacitive load.
Values are based on 10 pF capacitive load.
