JTAG Probes for OMAP and TMS320 DSP

ADA-JET-TI14

The Signum JTAG probe for OMAP devices, ADA-JET-TI14, provides a

physical interface between Signum emulators for the OMAP processor and

OMAP target boards. This probe is the same as that for the Texas Instruments

TMS320 devices. It has 14-pin double-row, polarized, .100" × .100". (2.54 mm ×

2.54 mm) female connectors. The pinout and dimensions of the probe are shown below (Figure 18 through

Figure 20

).

ADA-JET-TI14-LV

Your emulator can also be ordered with a low-voltage, or—if so desired—with both standard and low-

voltage—variants of the probe for OMAP devices. These two variants have slightly different dimensions

(Figure 19). The voltage range of the low-voltage probe is 1.8 – 3.3V (± 10%).
