PMC-UNIV-TEST-ENG has some modifications when compared with the standard
version. The B side PMC type connectors are added, the SCSI is removed, and the
testpoints are moved to the opposite side. In this configuation the PMC side connectors
can be installed into the host board, and the PMC can be installed into the carrier
connectors on the A side [now facing up]. The testpoints are now on the A side to make
them more convenient and provide a method of probing the PCI bus while the PMC is
installed into the carrier via PMC-UNIV-TEST-ENG.
“B” Front side with the PMC type connectors – “plugs into
host”
“A” Rear side with carrier type connectors to mate to PMC.
Note headers are this side for the –ENG configuration as it will be up to mate with the
PMC. The headers will be away from the PMC A secondary riser may be required with
cPCI etc depending on how low the PMC connectors are located to the bottom edge of
the carrier.
Special features
:
• Passive 32 bit Universal voltage design
• Bipass capacitors on all PMC power pins plus 10 uF on 5V and 3.3V.
• JTAG header routed to PMC connections
• PCI test points – easy to read staggered Silk labels both sides
• 8 grounds to support logic analyzer connection as well as ocilloscope
• User IO [Pn4] available through SCSI connector on standard model.
