5.4 Crystal Oscillator Circuit Setup for
Characterization
The following setup was used to measure the open loop voltage gain for crystal oscillator
circuits. The feedback resistor serves to bias the circuit at its quiescent operating point and
the AC coupling capacitor, Cs, is much larger than C1 and C2.
Figure 5.1 Crystal Oscillator Circuit Setup for Characterization
5.5 ESD Test Results
Test Description: ESD Testing was performed on a Zapmaster system using the
Human-Body-Model (HBM) and Machine-Model (MM), according to MIL-STD 883 and EIAJ
IC-121 respectively.
• Human-Body-Model stresses devices by sudden application of a high voltage supplied by a
100pF capacitor through 1.5k-ohm resistance.
• Machine-Model stresses devices by sudden application of a high voltage supplied by a
200pF capacitor through very low (0 ohm) resistance.
Test Circuit & Condition
- Zap Interval: 1 second
- Number of Zaps: 3 positive and 3 negative at room temperature
- Criteria: I-V Curve Tracing

5.6 Latch-Up Test Results
Test Description:
Latch-Up testing was performed at room ambient using an
IMCS-4600 system which applies a stepped voltage to one pin per device with all
other pins open except Vdd and Vss which were biased to 5Volts and ground
respectively.
Testing was started at 5.0V (Positive) or 0V (Negative), and the DUT was biased for
0.5 seconds.
If neither the PUT current supply nor the device current supply reached the
predefined limit (DUT=00mA, Icc=100mA), then the voltage was increased by
0.1Volts and the pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
Notes:
1.
DUT: The device under test.
2.
PUT: The pin under test.
