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.

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 stress devices by sudden application of a high voltage
supplied by a 100 PF capacitor through 1.5 Kohm resistance.
Machine-Model stresses devices by sudden application of a high voltage supplied
by a 200 PF 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 5 Volts and ground respectively.
Testing was started at 5.0 V (Positive) or 0 V(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=0 mA , Icc=100 mA), then the voltage was increased by 0.1 Volts and the
pin was tested again.
This procedure was recommended by the JEDEC JC-40.2 CMOS Logic
standardization committee.
Notes:
