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 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 Table 5.4 ESD Data Model Model S/S TARGET Results HBM Vdd, Vss, I/C 15 4000V Pass MM Vdd, Vss, I/C 15 200V Pass Page 12 of 17 AU9386 USB Flash Disk Controller V1.01W Official Release_ Public 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: 1. DUT: Device Under Test. 2. PUT: Pin Under Test.
