NAMC-EXT-RTM

The NAMC-EXT-RTM-F (with -F for front part of the MTCA system) is a passive extender card for standard AMCs in double-width form factor. It gives access to AMC modules from both sides in a running system.

All fabric connections as specified by the AMC.x and the additional I/O connector of the MTCA.4 specifications are supported and connected through from the MTCA backplane to the front of the NAMC-EXT-RTM-F. Test points for AMC and JTAG signals are marked on the PCB. Moreover, the extender allows access to the respective power planes for voltage and current measurements.

This enables users to easily check these voltages as well as to measure the power consumption of the AMC under test conditions.

There are a number of test points available on the extenders and all AMC signal identifiers are printed on the silkscreen. Using the NAMC-EXT-RTM-F, all test points on both sides (soldering and assembly side) of the AMC module are accessible in the testing mode. JTAG Test points for JTAG signals can be assembled with 100 mil header connectors.

The differential signals with up to 6.25 GHz frequency are available as small SMD test points. Other signals such as geographical address, IPMB signals are routed to standard test points allowing assembling with standard 100 mil header connectors.

As an assembly option, the board can be equipped with an on-board +3.3V power supply for generating +3.3V Management Power from +12V Payload Power, so the module under test can be operated with an external +12V power supply only (NAMC-EXT-RTM-F-PS).

The NAMC-EXT-RTM-R (with -R for rear part of the MTCA system) allows easy signal access to the front- and rear-site of an RTM module outside the chassis. It is connected to the NAMC-EXT-RTM-F /-PS via the I/O connector.

NAMC-EXT-RTM-F:

• Easy signal access to the front and rear side of an AMC module from outside the chassis
• Voltage and current measurement of Management and Payload Power
• Test points for soldering additional cables to measure all AMC signals
• Test points for JTAG interface

NAMC-EXT-RTM-F-PS:

• Additional 3.3V on-board power supply allows standalone mode of an AMC module (only 12V required)

NAMC-EXT-RTM-R:

• Easy signal access to the front and rear side of an RTM module from outside the chassis
