Products are grouped together by process for MTTF calculations.
(All XpressO output and package types are manufactured with the same process)
Number of Parts Tested:
360 (120 of each output type: HCMOS, LVDS, LVPECL)
Number of Failures: 0
Test Temperature:
125°C
Number of Hours:
2000
MTTF was calculated using the following formulas:
[1.] Device Hours (devhrs) = (number of devices) x (hours at elevated temperature in °K)
