Reliability Data Summary for DP8392 ~ REF: TEST LAB FILES TESTS PERFORMED RDT25406 RDT26627 Operating Life Test (OPL) (100'C; biased) RDT25500 RDT26638 Operating Life Test (OPL) (125'C; biased) RDT26562 Temperature and Humidity Bias Test (THBT) (85'C; 85% R.H.; biased) ABSTRACT Temperature Cycle Test (TMCL) (-40'C, + 125'C; unbiwere subjected to Operating Life Test, Temperature and DP8392 Coaxial Transceiver Interface parts from 8 lots ased) Humidity Bias Test, Temperature Cycle Test, and Electro- Electrostatic Discharge Test (ESD) (Human body model: static Discharge Test. R = 15000; C = 120 pF) PURPOSE OF TEST Evaluation of new device and qualification of U.K. fab. TEST SAMPLE DESCRIPTION/HISTORY Lot Device Package Date Fab Assembly Code Location Location 1 DP8392 N, 16 Leads 8509 NSSC NSEB 2 DP8392 N, 16 Leads 8513 NSSC NSEB 3 DP8392 N, 16 Leads 8526 NSSC NSEB 4 DP8392 N, 16 Leads 8552 NSSC NSEB 5 DP8392A(-4) N, 16 Leads 8620 NSUK 6 DP8392A(-5) N, 16 Leads 8637 NSUK 7 DP8392A(-5) N, 16 Leads 8637 NSUK 8 DP8392A(-5) N, 16 Leads 8637 NSUK RESULTS CONCLUSIONS 1. The DP8392AN exceeds the IEEE 802.3 specification of 1 million hours Mean Time Between Failure (MTBF). 2. U.K. fab results are comparable to those of Santa Clara. On ESD testing all pins passed at 1000V except for pin 7 (TX+).
