Figure 7 - Backplane Port Timing Diagram for 2, 4, 8, 16 and 32Mb/s stream rates
2.3
Backplane Frame Pulse Input and Master Input Clock Timing
The backplane frame pulse (FP8i) is an 8kHz input signal active for 122ns or 244ns at the frame boundary. The FPW
bit in the Control Register must be set according to the applied pulse width. See Pin Description and Table 16,
Control Register Bits, for details.
The active state and timing of FP8i may conform either to the ST-BUS or to the GCI-BUS as shown in Figure 6,
Local Port Timing Diagram for 2,4,8 and 16Mb/s stream rates, and Figure 7, Backplane Port Timing Diagram for 2,
4, 8, 16 and 32Mb/s stream rates. The MT90869 will automatically detect whether an ST-BUS or a GCI-BUS style
frame pulse is being used for the master frame pulse (FP8i). The active edge of the input clock (C8i) shall be
selected by the state of the Control Register bit C8IPOL. For the purposes of describing the device operation, the
remaining part of this document assumes the ST-BUS style frame pulse with a single width frame pulse of 122ns
and a falling active clock-edge, unless explicitly stated otherwise.
