PXI-100 Asset Intertech Controller Card

The Asset Intertech PXI-100 Boundary-Scan Controller Card enables boundary-scan test and programming in conjunction with other PXI/CompactPCI instruments for functional testing during board debug and manufacturing. The PXI-100 conforms to the popular 3U PXI form factor, adding a powerful new test tool in a small package to the extensive selection of test instrumentation that's already available for PXI\CompactPCI test systems.

The PXI-100 IEEE 1149.1 boundary-scan controller provides a sustained data throughput at high-test clock (TCK) frequencies, allowing for the fast application of test and in-system programming operations. The PXI-100 supports one Test Access Port (TAP) interface to the board and two TAP control modes. By supporting two different TAPcontrol modes, the PXI-100 can support non-compliant, boundary-scan devices and special board test operations. It uses the industry-proven Texas Instruments SN74LVT8980 embedded Test Bus Controller (eTBC) for dependable scan operations. The PXI-100 supports a controller-to-board distance of four feet without the use of an optional interface pod. A pod extends that distance to nine feet. At lower TCK frequencies, custom-built cables can extend the maximum distance to over 20 feet. The optional pod also expands the supported voltages from 3.3V (5V tolerant) to a range of 1.8V to 5.0V. The PXI-100 supports 16 individually controllable discrete I/O signals for controlling and monitoring non-boundary-scan signals.
