Real Time Clock

The IFE interface has a real time clock (RTC) to maintain date and time during power outage. The expected life time of the RTC is 15 years when operated at intermediate mode (in this mode, the battery is operated continuously for 4 days with an interval of 45 times over a period of 10 years).

The IFE interface must maintain a crystal tolerance of ±20 ppm (typical)/±150 ppm (maximum) during the period of 15 years at -25 °C (-13 °F) to 85 °C (185 °F). The time drift by RTC chip varies from -16 s/day to +2 s/day. During power recycle, the RTC is able to maintain the date and time settings.
