3U VPX Development Chassis:
DK3 “El Sharko”
Supporting VPX and SOSA Aligned Payload Integration
The DK3, “El Sharko” is a flexible bench top platform providing thescalability to support rapid development, demonstration andevaluation of 3U VPX and SOSA aligned systems.
It enables shortened design cycles for faster time to deployment.
The DK3 allows fast backplane replacement and fast conversion
between air and conduction cooled slot inserts.
The open frame design includes backplane, power supply, fancooling and rear transition slots in support of a variety of testfunctions.
The DK3 comes standard with an 8 slot, 1.2" pitch power and ground
40Gb backplane to support your development efforts. The DK3 has abalanced 12V / 5V power supply for mixed power payloads and a 12V
centric power supply is available on request. Both support current
and emerging VPX and SOSA aligned module power requirements.
The DK3 is part of Amphenol’s development solutions supporting
VPX system development and the hardware convergence andinteroperability initiatives of the US Department of Defense.

BACKPLANESThe DK3, “El Sharko” includes as standard an 8 slot 40Gb capable power and ground pass through backplane with 4 x fully
populated slots and 4 x slots with VITA 67 full width apertures. Apertures allow installation of VITA 66 / 67 connectors for
optical and RF connectivity. Systems can be supplied with or without the required connectors installed.

Slots 1-4, VITA 67.3 apertures for fill and half
width VITA 66 & 67 optical and RF connectivity
Power and ground or pass through backplanes are also referred to as uncommitted backplanes. Uncommitted VPX andSOSA backplanes rely on a slot to slot cabling system to establish the data, control, and expansion planes necessary for
integration testing. The backplane in the DK3 includes slot to slot connectivity for power, and ground plus VPX-Standard
system signals such as a system reset and reference clocks

AIR AND CONDUCTION COOLED CONVERSIONThe DK3 supports air cooled VITA 48.1 or conduction cooled VITA 48.2 VPX or SOSA aligned plug in cards. Quick
conversion air, or conduction cooled card guides, allow slot by slot configuration for mixed payloads. Slot
conversion can be completed in minutes to support both card types as needed.
