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
 Critera : I-V Curve Tracing
Model Model S/S TARGET Results
HBM Vdd, Vss, I/C 15 4000V Pass
MM Vdd, Vss, I/C 15 200V Pass

ELECTRICAL CHARACTERISTICS 14
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.
