VTX989

The VTX989 is a five slot 3U VPX conduction cooled chassis. The chassis can accept four standard 3U VPX conduction cooled modules with 5HP pitch. The P2 connector location is populated with a 8-position VITA 67.2 coaxial/RF module for the first four modules (the backplane can be modified to meet any of the VITA specifications).

The VTX989 fifth slot is for a modified VPX 3U module allowing the hottest module within the chassis to dissipate heat directly through the skyline made on the cold wall. This allows the best heat transfer from the hottest module directly to the cold wall. All I/O are routed to the front of the chassis and the VITA67.2 can be routed through coaxial via the rear. The I/O’s are customized and are based on customer requirement.

Power Supply

The VTX989 has an integrated 250W Power Module which takes a +28V input and provides the necessary powers to the 3U VPX module in accordance with VITA 46 specifications. The power module also dissipates heat directly through the cold wall.

Backplane

The backplane provides all the necessary VITA 46 signals set by the user (NVMRO, SYSRESET, SYS_CON, driver the dual clock, etc.). In most cases the backplane default routing has to be modified to fit module profiles.
