The Advanced Telecom Computing Architecture [ATCA or AdvancedTCA] specification is designed to be used in central office grade equipment [the telecommunications sector]. ATCA, uses an 8U [322.25mm high x 280mm deep] card [Blade] size, spaced 1.2" apart [6HP pitch]. The ATCA specification defines the Rack and chassis [Shelf] form factors, [passive] backplane, cards, power, Keying... The electo-mechanical specification is based on IEC60297. An ATCA card can handle up to 4 PMC daughter cards.
AdvancedTCA (PICMG 3.x) [Advanced Telecom Computing Architecture]
PICMG 3.0 Mechanical, Power, Connectors, Specification
PICMG 3.1 Specification for Ethernet fabric interconnects
[10/100/1000 Ethernet]
PICMG 3.2 Specification for InfiniBand fabric interconnects [16 slot
backplane]
PICMG 3.3 Specification for StarFabric interconnects
PICMG 3.4 Specification for PCI Express interconnects
VITA 34 Embedded Modular; is similar to AdvancedTCA and also
adopts an 8U x 280-mm form factor.

SwitchedFabric Buses
page.
Of course for all other IC types, see this page: Semiconductors Manufacturers
ATCA chassis [or shelf] are designed to function in a normal ANSI/EIA 310 cabinets (IEC 60297-1, and 60297-1). The chassis are 12U high to support 8U high boards. Up to three 12U chassis will fit into a 42U rack. The chassis has a 1.75U (high) air plenum below the card cage and a 2.25U (high) space above the cage for dual (hot swappable) blowers. The standard chassis width is 19 inch [supporting up to 14 CCAs], or 23 inch [supporting up to 17 CCAs]. Dual redundant 48 volts power is supplied to the boards. DC/DC converters local to each board are used to provide the required voltages. Each board may dissipate up to 200 watts. 60 volt systems may also be used.
The following page lists ATCA Chassis Manufacturers.
Three styles
Z1 [Zone 1]: Power/Management
Z2 [Zone 2]: Data Interface (which consist of 5 ZD connectors;
each is 4 rows x 10 columns of shielded differential pin pairs)
Z3 [Zone 3]: Rear panel interconnect [Rear Transition Module]
Positronic Industries {AdvancedTCA computing platform Zone 1 power connector. PICMG 3.0}
Tyco Electronics {ATCA Power Connectors, Zone 1}
Erni {Male/Female AdvancedTCA Zone 2}
The pin out for the Advanced ATC back plane is TBD at this point, but will be added when I get a chance.
