The DSP is connected to the ELIC0, Ports 0, and to the ELIC1, Port1, via a PCM-DSP
Interface Unit (PEDIU). Figure 2-31 shows the IOM-Port Multiplexer in Mode 1.
Figure 2-31 PEDIU Connection to the ELICs
• The DSP can be connected to both ELICs or to ELIC0 only (via IN0 and OUT0).
• ELIC0 and ELIC1 can be programmed for FSC and DCL be input or output clocks,
Note: If FSC/DCL are outputs of the ELIC0/1, only the outputs of ELIC0 drive the port
• PEDIU Data Clock = DCL0 or PDC4 or PDC8
• PEDIU Frame Sync Clock = FSC0 or PFS
depending on the system requirements.
PDC8 requires a DSP clock of 40 MHz.
