Accurate MEMS Real-Time Clocks Product Guide
Video Security and Surveillance
Security and Surveillance Systems Benefit from Accurate Timestamping and
Small Size of RTC Products
Accurate timestamping of event data is an important aspect of video security and surveillance systems. MEMS-based
RTCs further enhance this by providing timekeeping accuracy far exceeding the most robust crystal designs. Besides less
aging, Maxim Integrated’s MEMS-accurate RTC products support accuracy and stability standards of much less than
±5ppm lifetime over voltage, temperature, and time. This translates to less than ±0.432 seconds/day, much better than ±3
minutes/year. A smaller product package size (8-pin SO) provides users with small footprint solutions to accommodate
space-constrained designs. Power consumption of < 3.5μA make the devices suitable for battery-backed applications.
