PMC Slots Functional Description
CPCI-6115 CompactPCI Single Board Computer Installation and Use (6806800A68D) 83
from the PMC J14 connector to the CompactPCI J3 I/O connector while the PMC J24 connector
signals are routed to the CompactPCI J5 I/O connector. Both PMC I/O connectors are routed
to their respective CompactPCI I/O connector following the PIM differential signalling
recommendations. The CPCI-6115 front panel allows for front I/O through the PMC faceplate.
PMC slot 1 supports:
z Mezzanine Type: PMC = PCI Mezzanine Card
z Mezzanine Size: S1B = Single width and standard depth (75mm x 150mm) with front panel
z PMC Connectors: J11, J12, J13, and J14
z Signaling Voltage: +5 V
z Supported modes: 32-bit, 33 MHz PCI
z I/O: front panel and CompactPCI J3 rear panel
PMC slot 2 supports:
z Mezzanine Type: PMC = PCI Mezzanine Card
z Mezzanine Size: S1B = Single width and standard depth (75mm x 150mm) with front panel
z PMC Connectors: J21, J22, J23, and J24
z Signaling Voltage: Vio = +3.3 V (+5 V tolerant) or +5 V, selected by keying pin
z Supported modes: 32/64-bit 33/66 MHz PCI or 66/133 MHz PCI-X
z I/O: front panel and CompactPCI J5 rear panel
In addition, the PMC connectors are located such that a double width PMC may be installed in
place of two single PMCs.
In this case, the CPCI-6115 supports:
z Mezzanine Type: PMC = Mezzanine Card
z Mezzanine Size: double width and standard depth (150mm x 150mm) with front panel
z PMC Connectors: J11, J12, J13, J14, J21, J22, J23, J24
z Signaling Voltage: +5 V
z Supported modes: 32-bit 33 MHz PCI
z I/O: front panel and CompactPCI J3 rear panel
The following special-function processor PMC pins, as defined by the draft Processor PMC
Standard VITA 32-199x, are implemented on the CPCI-6115 as described in the following
sections.
