JTAG Isolation Adapter for
TMS320 / 470 / 570 Devices
from Texas Instruments
ADA-ISO-TI14
is a full isolation JTAG probe for
JTAGjet emulators which reduces the chance of damage
to the emulator associated with ground loops, voltage
spikes, electrostatic discharge (ESD) and noise on power
and ground lines generated by high-current motors and
other machinery.
The probe can be powered from the target board (default)
or from an external isolated 5V power supply (optional) if
the target cannot deliver the extra 100mA needed by the
probe.
Features:
Supports all TMS320C2000, C5000, C6000,
OMAP, DM and TMS470 / 570 devices
Operating JTAG voltage from 3.3V to 5V
Galvanic isolation up to 1000 V (peak)*
50kV/µs transient immunity (typ.) on JTAG lines
ESD protection of 8kV on contact and 15kV air
discharge
Maximum JTAG clock rate up to 15MHz

Important Notice about Isolation & Safety
* Isolation of 1000V cannot be provided for more than 1
sec. The continuous, safe normal operating voltage
across the isolation barrier is 0 - 60VDC. The isolation
voltage represents a measure of immunity to transient
voltages and the adapter should never be used as an
element of a safety isolation system. The adapter can be
expected to function correctly with 300 volts offset
applied continuously across the isolation barrier, but then
the circuitry on both sides of the barrier must be regarded
as operating at an unsafe voltage and further
isolation/insulation systems must be used according to
safety standard requirements.
Signum Systems will not be liable for any damages
resulting from usage of this adapter.
