2.2 Board-Level Interfacing Diagram
The following figure demonstrates the interfacing structure between the internal processing
modules of the PMC240 and other major PMC240 system components. Where PMC240 sys-
tem elements have common interfacing they are grouped into a block. Interfacing common to
only one element of a block is indicated with a direct connecting line. The interfacing lines are
shown in white where they are on board and in black for board external interfacing.
The “*” (asterisk) in the figure blocks indicate that the actual implementation depends on the
system configuration and the PMC240 variant employed. As a minimum, at least one channel
of up to 1000Base-T capability is available. A maximum of two channels of the same or varying
link type can be implemented. Flash memory is always an optional feature which must be stip-
ulated along with the variant.
Legend for Figure 2-1:
• GALV.ISOL. = galvanic isolation for copper links
• SC TRCV = SC-type transceiver for fiber optic links
• CAT5 UTP = category 5, unshielded twisted pair cabling (copper links)
• T/R FO = transmit and receive fiber optic links
As the Gigabit Ethernet controller provides automatic detection of the Ethernet standard in use
on copper links the PMC240 may be used with any mix of Ethernet networks from 10Base-T to
1000Base-T.
