Time-Division Multiplex (TDM) Bus
Four streams of TDM data are available for connection to an external host board and are connected to all
MSC711x DSP devices. The streams connect to J3 of the PDK CMC site and J6, J7, and J8 of the MDS
CMC site. One pair of frame and clock signalling is provided for all TDM streams. Streams CT_D1 and
CT_D5 must be used for TDM streams from the external host to the DSP farm. Streams CT_D0 and
CT_D4 must be used for TDM streams from the DSP farm to the external host. The frame and clock
signals are buffered and then connected to each DSP device. The CT_D0, CT_D1, CT_D5, and CT_D4
signals are connected directly from the DSP devices to the CMC connectors. Figure 6 shows the TDM
stream connections on the board.
