With modern signal families operating on lower logic level
swings and based on current switching rather than the voltage, it is
mandatory to provide active termination for the signals at the receiver
side of the line. HiLevel Technology Inc. announced today a new feature
available with the Griffin III family of IC testers. The pin
electronics drivers are now capable of producing three distinctive
voltage levels, and with fixed 50ohm output impedance this facilitates
high-speed active termination for single-ended as well as differential
(split) signals.
This fully
programmable and flexible solution
eliminates any need for custom termination circuits on the DUT
Interface
Board,
reducing engineering development time, any additional parts,
instruments or
control signals as well as debuging and maintenance costs. All the
settings are
saved with the test setup and later can be modified, disabled or
enabled at any time, depending on user needs. Termination voltage
settings
can be
included as a part of the test procedure (for example in DC PMU or
Shmoo plot) for
functional test or device characterization, which is impossible with an
external
circuit.
Both the driver and comparators are located on a
single chip. The termination is provided directly at the comparator
input thus eliminating any stubs or signal degradation, even for the
most demanding configurations. This unique
feature cannot be achieved using
external components. The third voltage is per pin
programmable, covering full voltage swing range from –1.5V up to +6.5V
with 5mV resolution and operates on all available test rates. This
feature can be enabled for selected pins while other pins can operate
in standard driver high impedance mode.
