FACT Noise Characteristics
The setup of a noise characteristics measurement is critical
to the accuracy and repeatability of the tests. The following
is a brief description of the setup used to measure the
noise characteristics of FACT.
VOLP/VOLV and VOHP/VOHV:
• Determine the quiet output pin that demonstrates the
greatest noise levels. The worst case pin will usually be
the furthest from the ground pin. Monitor the output voltages using a 50Ω coaxial cable plugged into a standard
SMB type connector on the test fixture. Do not use an
active FET probe.
Equipment:
Hewlett Packard Model 8180A Word Generator
PC-163A Test Fixture
• Measure VOLP and VOLV on the quiet output during
worst case transition for active and enable. Measure
VOHP and VOHV on the quiet output during the worst
case active and enable transition.
Tektronics Model 7854 Oscilloscope
Procedure:
1. Verify Test Fixture Loading: Standard Load 50 pF,
500Ω.
• Verify that the GND reference recorded on the oscilloscope has not drifted to ensure the accuracy and repeatability of the measurements.
2. Deskew the HFS generator so that no two channels
have greater than 150 ps skew between them. This
requires that the oscilloscope be deskewed first. It is
important to deskew the HFS generator channels
before testing. This will ensure that the outputs switch
simultaneously.
VILD and VIHD:
• Monitor one of the switching outputs using a 50Ω coaxial
cable plugged into a standard SMB type connector on
the test fixture. Do not use an active FET probe.
3. Terminate all inputs and outputs to ensure proper loading of the outputs and that the input levels are at the
correct voltage.
• First increase the input LOW voltage level, VIL, until the
output begins to oscillator steps out a min of 2 ns. Oscillation is defined as noise on the output LOW level that
exceeds VIL limits, or on output HIGH levels that exceed
VIH limits. The input LOW voltage level at which oscillation occurs is defined as VILD.
4. Set the HFS generator to toggle all but one output at a
frequency of 1 MHz. Greater frequencies will increase
DUT heating and effect the results of the measurement.
• Next decrease the input HIGH voltage level, VIH, until
the output begins to oscillate or steps out a min of 2 ns.
Oscillation is defined as noise on the output LOW level
that exceeds VIL limits, or on output HIGH levels that
exceed VIH limits. The input HIGH voltage level at which
oscillation occurs is defined as V IHD.
• Verify that the GND reference recorded on the oscilloscope has not drifted to ensure the accuracy and repeatability of the measurements.
VOHV and VOLP are measured with respect to ground reference.
Input pulses have the following characteristics: f = 1 MHz, tr = 3 ns, tf =
3 ns, skew < 150 ps.
FIGURE 1. Quiet Output Noise Voltage Waveforms
5. Set the HFS generator input levels at 0V LOW and 3V
HIGH for ACT devices and 0V LOW and 5V HIGH for
AC devices. Verify levels with an oscilloscope.
