Figure 28 - TDM Bus Master Mode Timing at 2.048 Mbps
12.2 TDM Interface Timing - H.110 Mode
These parameters are based on the H.110 Specification from the Enterprise Computer Telephony Forum (ECTF)
1997.
Note 1:
Note 2:
Note 3:
Note 4:
Note 5:
TDM_C8 and TDM_FRAME signals are required to meet the same timing standards and so are not defined independently.
TDM_C8 corresponds to pin TDM_CLKi.
t
DOZ
and t
ZDO
apply at every time-slot boundary.
Refer to H.110 Standard from Enterprise Computer Telephony Forum (ECTF) for the source of these numbers.
The TDM_FRAME signal is centred on the rising edge of TDM_C8. All timing measurements are based on this rising edge
point; TDM_FRAME corresponds to pin TDM_F0i.
Phase correction (
Φ
) results from DPLL timing corrections.
