Transceivers ease boundary scan
integration
SFX-TAP(x)/FXT transceivers are the latest addition to the Scanflex JTAG/boundary scan hardware platform.
SFX-TAP(x)/FXT transceivers are the latest addition to the Scanflex JTAG/boundary scan hardware platform These all-new Scanflex TAP transceivers (SFX transceivers) we developed for the integration into in-circuit testers (ICT) and optionally offer two, four, six or eight parallel, independent TAPs as well as a series of additional resources and special functions

Test card simulates automotive switching
A new PXI card provides switch simulation and state monitoring of digital signals in automotive engineering applications.
"The combination of JTAG/boundary scan with ICT or other fixture based test technologies is the most efficient solution for many medium and high volume applications", says Bettina Becker, Marketing and International Sales Manager for Goepel Electronic.
"The new Scanflex transceivers are our response to customers' requests for professional integration solutions with specific production demands".
"Our OEM partners and third party applicants are now able to utilise strong boundary scan options for boards with limited physical test access".

One card tests multiple automotive buses
New from Goepel Electronic is a novel multiple-bus controller card for automotive applications worldwide.
"Additionally, they are able to integrate the entire test and programming procedures from the lab directly into the production process".
In contrast to previous Scanflex TAP transceivers, instead of having integrated interface cards, the new models are differentially coupled an IDC or wire wrap cable which can be up to 2m long.
Even with high frequency signal transitions, trouble-free TAP signal transmission to the TIC02 modules is guaranteed at up to 80MHz.
These TIC02 units are low-cost modules providing externally programmable input and output voltage per TAP as well as relays for the galvanic isolation from the UUT.
Furthermore, there is a mechanism to adapt the interface to various driver requirements.
For each TAP there is a programmable delay compensation combined with stepwise (250Hz/1MHz) programmable clock frequency to 80MHz.
Moreover, resources such as 32 voltage programmable dynamic I/Os, two analogue I/O channels, three statistic I/O and trigger lines are standard features of the SFX-TAP(x)/FXT transceivers, which can be freely combined with any Scanflex controller via PCI, PXI, USB, FireWire or LAN, with distances up to 5m.
The new transceiver has a slot for coupling with Scanflex I/O modules.
Alternatively, various SFX I/O modules can be connected via an SFX/LS interface.
These extensions allow the configuration of almost unlimited additional analogue or digital resources.
The SFX-TAP(x)/FXT is fully supported in the System Cascon JTAG/boundary scan software from version 4.2.1 on, and is compliant with IEEE1149.1, IEEE1149.4, IEEE1149.6, IEEE1532 and JESD71 standards.
The software automatically recognises the transceiver using its autodetect feature. Request a free brochure from Goepel Electronic ...
