Manfred Schmitz (MEN) was born in Nuremberg, Germany. He completed his studies in communication engineering at Georg-Simon-Ohm University of Applied Sciences in Nuremberg in June 1981. After that he studied physics for several semesters at the Erlangen/Nuremberg University as well as several semesters of computing sciences at the Open University of Hagen
Manfred Schmitz founded MEN Mikro Elektronik GmbH in 1982 as one of three partners and has since been the Technical Director of the company.
Roland Nuiten (3M) received his M.S. in Electrical Engineering from the Technical University of Eindhoven, NL in 1994. He is currently employed by 3M in Neuss, Germany as an Advanced Engineering Specialist in 3M’s Electronic Solutions Division.
Roland has over 10 years of high speed interconnect design experience with 3M, Tyco and AMP. He is currently responsible for the development and support of 3M HS interconnects.
CompactPCI® PlusIOPICMG 2.30 is a supplement to PICMG 2.0
CompactPCI® PICMG 2.0 PICMG 2.0 gives no electrical specification for user I/O pins on the backplanes – so-called
BP(I/O) signals The HM connector does not support high-speed differential signals like PCI Express® or
SATA CompactPCI® PlusIO PICMG 2.30 extension
CompactPCI® PlusIO PICMG 2.30 extension: PICMG 2.30 adds a standard pin-out for BP(I/O) signals for serial high-speed interconnects PICMG 2.30 introduces a fully compliant high-speed connector which promotes the use of
BP(I/O) pins for high-speed signals without adding additional ground pins
PICMG 2.30 defines the usage of rear I/O pins of the 32-bit CompactPCI®system slots for high-speed serial signals.
This allows interoperability with other CompactPCI® 2.xx standards by PICMG for 3U as well as for 6U cards which do not use these pins.
For these high-speed signals, a new J2 connector is introduced which is designed to be intermateable to backplanes defined in PICMG 2.0. This connector is able to support differential signals up to 5 Gb/s.

Focus of CompactPCI® PlusIO
J2 I/O Pin Assignment
®
This means system slot boards with this new high-speed connector can be used in existing systems.
The pin assignment also interoperates with 64-bit backplanes• 32-bit accesses will work, • 64-bit will not work in such an environment,• Serial interconnect is not usable
One main advantage of the combination of legacy PCI and modern serial buses on J2/P2 is to realize hybrid systems.
These point-to-point connections are optimized depending on the connected devices.
• For closely coupled extensions, PCI Express® was introduced to replace the parallel PCI bus.
• For hard drives, SATA or SAS were established.• Slower, not so closely coupled devices are connected by USB• For multiprocessing applications, Ethernet is the most common solution to
The CompactPCI® PlusIO specification defines the user-defined pins of the 32-bit system slot definition in a way to bring out the serial interconnections on J2 to the backplane.
This definition does not violate the existing standard so that the two are fully interoperable.
The standard J2 (2-mm HM connector) is not able to support differential signals up to PCI Express® generation 2 (5 Gb/s). So the connector used for J2 is improved as well
The backplane connector does not need to be modified A hybrid backplane can be realized by combining a CompactPCI®
system slot together with CompactPCI® Plus and / or CompactPCI® Express peripheral boards.
The UHM connector offers the ability to support high-speed differential signals in 2mm HM systems without costly backplane and daughter card re-designs.
The UHM connector is a shielded HM socket, intermateable and footprint compatible to HM sockets with superior impedance control and crosstalk reduction.
The 3MTM Ultra Hard Metric (UHM) Socket Connector’s internal coaxial type shielding is connected to ground on the PCB through the f/z-row. Two options are available: Every odd pin is connected (f) or all pins are connected (f/z).

2 mm Hard Metric Standard Connector System 2 mm x 2 mm contact interface 5 row: 2 mm x 2 mm PCB footprint (A, B, CL,CR, AB) 8 row: 1.5 mm x 2 mm PCB footprint (D, E, FL, FR, DE)
The 3MTM Ultra Hard Metric (UHM) Socket Connectors, 5-row and 8-row, are available today.
Work is ongoing on a UHM header for further increased system performance with the same design goals and philosophy: to have internal shielding for higher performance and optimum ground connection, but still be foot print compatible to 5+2 HM headers.

Question & Answer Session1. When will PICMG 2.30 be released as final? (Manfred)
2. What is so special about the 3MTM Ultra Hard Metric (UHM) Socket Connector? Is it not just a standard 2mm HM? (Roland)
3. The following sentence does not make sense. If f/z shield configuration for pairs horizontal in rows, is the SI data available? Also, are the horizontal shields configurable or do they have to be loaded in every position? (Roland)
4. What are expected to be the most common applications driven by next generation CompactPCI? (Manfred)
5. Is there a plan to drive the UHM socket connector to even higher speeds like 10 Gbps+ staying on the 2mm footprint? You said something about a UHM header planned? (Roland)
