JT 5705 Mixed-Signal JTAG Tester

The JT 5705 series offer a unique combination of JTAG TAP controller (tester) interfaces plus digital and analog I/O in compact desktop package.

Use the ‘mixed-signal’ features to measure power supplies, clock frequencies or test DACs and ADCs. Add your own capability through use of CoreCommander FPGA our generic bridge/translator system.

The JT 5705/USB version (pictured right) is a desktop model with 2 TAPs and 64 I/O making it ideal for hardware validation or small-scale production test. Maximum TCK speed is 15 MHz and all voltages are fully programmable. The JT5705/FXT is the ‘fixture’ version supplied as a pcb assembly only with optional ‘break-out’ boards available depending on your application.

Features

  • 2 TAPs
  • Up to 64 MIOS Channels
  • Measures Frequency
  • Up to 8 Analog IO
