Serial Interface Modules (SIM)

MXSYNC# is clocked out using the falling edge of MXCLK and MDXO is clocked out with the
rising edge of the MXCLK. MXDI is sampled at the rising edge of MXCLK (the CPCI-6020 MTB
synchronizes MXDI with MXCLK's rising edge). The timing relationships among MXCLK,
MXSYNC#, MXDO and MXDI are illustrated by the following figure:

4.20 Serial Interface Modules (SIM)
The synchronous serial ports on the CPCI-6020-MCPTM-01 are configured via serial interface
modules (SIMs), used in conjunction with the appropriate jumper settings on the transition
module. The SIMs are small, plug-in printed circuit boards which contain all the circuitry needed
to convert a TTL-level port to the standard voltage levels needed by various industry-standard
serial interfaces, such as EIA-232, EIA-530, etc.

PMC Interface Module (PIM)

The CPCI-6020-MCPTM-01 provides additional I/O capabilities for the CPCI-6020. There are
two distinct groups of I/O passed from the CPCI-6020 to the CPCI-6020-MCPTM-01 through
the CompactPCI J3 and J5 connectors, CPCI-6020 host I/O and PMC I/O. The host I/O
functions are designed into the CPCI-6020 and their presence or absence is determined when
that board is built. This I/O cannot be configured at the system integration level. PMC I/O
