GÖPEL Launches JTAG Transceiver For Flying Prober Integration

Jena, Germany -- GÖPEL electronic, vendor of JTAG/Boundary Scan solutions compliant to IEEE Std. 1149.1, is launching an additional component to the Boundary Scan hardware platform SCANFLEX. SFX-TAP4/CR is the newest member of SCANFLEX TAP transceivers (SFX Transceiver), developed especially for integration in Flying Probe Testers (FPT) offering four parallel independent TAP as well as a set of additional resources and special functions.

"In our opinion, Flying Prober test technology is not only becoming more attractive but means a perfect addition to our Boundary Scan technique," says Bettina Becker, Marketing and International Sales Manager for GÖPEL electronic. "These new SCANFLEX® transceivers are the logical response to the increasing demand for professional integration solutions in particular for production requirements. Our OEM partners now have an improved Boundary Scan option for boards with heavily reduced test access."

SFX-TAP4/CR is already the seventh SCANFLEX TAP transceiver, and can be freely combined with all SCANFLEX controllers on PCI, PXI, USB or LAN basis, with distances up to five meters. Each single TAP offers programmable input and output impedance, stepwise (250Hz/1MHz) programmable TCK frequency to 80MHz, programmable delay compensation, read-back of output signals, and a relay controlled power signal. This versatility enables an optimal UUT configuration even over distances up to 1.5m. All TAP feature captive CIONTM interface chips (ASIC) and additional safety measures. Furthermore, resources such as thirty-two voltage programmable dynamic I/O, two analog I/O channels, three statistic I/O and trigger lines are standard features.

All TAP signals and PIO channels are galvanically isolated from the UUT, and can be tested for operation directly in the system by means of an integrated Built-In-Test (BIT). That means a reduced diagnostic effort for faults without manipulating the Flying Prober system.

The new transceiver has a particular 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 analog or digital resources.

SFX-TAP4/CR is fully supported in the industry leading Boundary Scan Software SYSTEM CASCON from version 4.2.1 on and is compliant with standards IEEE 1149.1, IEEE 1149.4, IEEE 1149.6, IEEE 1532 and JESD71. The software automatically recognizes the transceiver by the AutoDetect Feature.
