SFX-TAP(x)/FXT, transceivers are additional components to the JTAG/Boundary Scan hardware platform Scanflex. The TAP transceivers (SFX transceivers) were developed for integration into in-circuit testers (ICT) and optionally offer 2, 4, 6 and 8 parallel, independent TAPs as well as additional resources and special functions.
In contrast to previous Scanflex TAP transceivers, the new models’ TAP Interface Cards (TIC) type 02 are no longer integrated but are differentially coupled with an up to 2 metres long IDC or Wire Wrap cable. Even at high frequency signal transitions, a TAP signal transmission to the TIC02 modules of up to 80 MHz is guaranteed. The low-cost modules provide 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 TCK frequency to 80MHz.
Features include 32 voltage programmable dynamic I/O, two analog I/O channels and three statistic I/O and trigger lines.
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 analog or digital resources.
