High-speed embedded computing 3U VPX backplane for mixed payload modules introduced by Elma
FREMONT, Calif., 21 Nov. 2016. Elma Electronic in Fremont, Calif., is introducing a high-speed embedded computing3U VPX backplane that supports integration of mixed payload modules, including commercial off-the-shelf (COTS) single board computers, switches, and RF payloads for computer architectures used by the DOD's Hardware/Software Convergence Initiative.
This backplane supports high-speed signals on data paths as well as VITA 67.3 connectors compatible with legacy VITA 67.1 and VITA 66.4 RF and optical I/O connectors.
This 3U 12-slot VPX backplane has a radial slot card for timing and synchronization, and includes seven slots that receive radial clock signals (Aux Clk and Ref Clk) driven independently from a radial clock timing card. The remaining five slots receive standard VPX bused Aux_Clk and Ref_Clk signals. The timing card slot also supports a VITA 67.3c connector with 10 SMPM cavities.
The backplane can handle VPX connector data rates through its multiple data plane UTP connections at 10 GBASE-KR data rates and 10 GBase-KR UTP control plane connections.

The backplane also has four payload slots, each equipped with a combination VITA 67.3c optical and RF connector in the J2 position. The slot two switch supports a VITA 67.3d connector module compatible with a payload module fitted with a VITA 66.4 MT optical ribbon connector or a VITA 67.1 RF coaxial connector.
When equipped with optical interfaces, the VPX architecture enables data rates across the backplane that are faster than copper interconnect. Also included is a 12-cavity, VITA 67.3e connector to support an RF switch card.
The backplane has two additional slots for plug-in power supplies but is also designed with power input threaded studs so either power input method can be used. The backplane can be supplied in a mini ATR style chassis.
