onTAP USB JTAG Cable
The onTAP USB test and programming cable is the link between onTAP and your application, using flying leads, Xilinx type header, or Altera type header.
Connect the onTAP USB cable to your application with either the Xilinx style header, flying leads, or an Altera style header. The onTAP cable automatically senses and adjusts to target I/O voltages, and interfaces to devices operating at 1.8 to 5.0 VDC using the VREF Voltage from the target chain. This facilitates easy configuration to many different JTAG ports, which is helpful in design and manufacturing. Features include:
- Adjustable TCK Clock
- Auto sensing voltage through VREF for devices operating from 1.8V to 5V
- Connect to popular Xilinx and Altera style headers, or use flying leads
- Program Flash
- Test and program multiple chains
- Hot plug and play
Includes High Speed, 6′ A-A USB Cable and your choice of connector: Flying Leads, Xilinx Header, or Altera Header.
