Goepel Makes Boundary Scan Apps Interference-Free
TAP isolator for boundary scan.
Jena, Germany — Goepel electronic is introducing the TAP-Isolator, a special module to improve interference immunity in serial scan operations. The newly developed hardware was specifically designed for applications in critical signal environments needing potential isolation, enabling a complete galvanic insulation of the Test Access Port (TAP) transceiver from the target.

The TAP-Isolator is a small stand-alone box that can be used as add-on hardware in each scan path. It separates the transceiver's primary TAP interface from the target's secondary TAP interface, and is easily upgradable at any time.

The potential isolation eliminates mutual interference between TAP transceiver and target. That means an increase in the functional safety of Boundary Scan applications such as interconnection test, PLD programming or Flash programming.

The TAP-Isolator can be operated on the secondary side with fixed or variable output voltage between 1.8V and 4.5V, and maximum transmission frequency of 70MHz. It supports all standard TAP signals (TCK, TMS, TDI, TDO) as well as the optional /TRST. The isolation hardware's possible runtime delays when used with today's Boundary Scan systems such as SCANFLEX® can be individually compensated per TAP by the integrated ADYCS technology. Additionally, the TAP-Isolator can be run with all JTAG controllers from Goepel electronic, e.g. PicoTAP and SCANBOOSTER, as well as other vendors.
