JTAG Isloation Protection

The Blackhawk Isolation Adapter is a device that connects between your JTAG Emulator and the JTAG connector on your target board. The adapter is designed to minimize and protect connected devices (PC/Emulator/Target) from ground loop voltage, harsh environments and new, untested designs. The Isolation Adapter supports 3.3-5.0v targets and is available with standard TI 14-pin or compact TI 20-pin JTAG connections.

 

Pricing & Availability


Description

The isloation adapter is a straight forward, easy to use product. Just connect it between your emulator's JTAG socket and the target board's header. These adapters can be used with most JTAG emulators, including XDS200, XDS510, XDS560 and XDS560v2 models.

Blackhawk offers two models. A 14-pin version and 20-pin version. Both models are identical except for the JTAG connections. Select the model that fits your needs. These adapters can also be used with a pin converter in the event that your JTAG connections do not match up identically with either of these models.

The adapter does expect the target board to provide up to 100 mA of 3.3 or 5.0 volts on JTAG pin 5 (TVD) to power the adapter's components.


Features

  • Supports I/O voltages of 3.3v/5.0v targets
  • Works with any XDS510 or XDS560-class emulator
  • Designed using UL60950 and UL1577 standards
  • High Speed operation: up to 20MHz TCK
  • 25kV/┬Ás transient immunity
  • Powered by target board's JTAG pin 5 (TVD)
  • Current consumption is 60-80mA nominal (100mA max)
  • Digital Isolators Used: SI844x and ADuM1250.


Benefits

  • Protects emulator investment.
  • 1,500 Vrms Galvanic Isolation Voltage
