Introduction
Advancing Timekeeping Accuracy
In 1999, Maxim Integrated introduced the DS32kHz, a 32.768kHz temperature-compensated crystal
oscillator (TCXO), which was the industry's first accurate timekeeping product for real-time clock
(RTC) applications. The product boasted an accuracy of ±7.5ppm across the entire -40°C to +85°C
industrial temperature range.
By 2005, with the combination of innovative packaging technology and improved temperature sensor
capability, we introduced what would be considered the industry’s most accurate RTC, the DS3231S,
an extremely accurate I²C-integrated RTC/TCXO/crystal. The DS3231S featured a highly reliable and
innovative package that incorporated a 32kHz tuning fork crystal into a standard 16-pin, 300-mil SO.
This highly integrated device further enhanced timekeeping accuracy by providing a frequency accuracy
of less than ±3.5ppm over the -40°C to +85°C temperature range. This accuracy is equivalent to less
than ±0.3 seconds/day.
In 2009, Maxim Integrated embarked on a goal to create a quantum leap in technology advancement
by developing an RTC that would exceed the performance of the DS3231S, but provide it in a smaller
package with lower cost, higher accuracy standards, and substantially more ruggedness. The culmination
of this work is a product family based on microelectromechanical systems (MEMS) technology.
The
company’s development goals. The device has a timekeeping accuracy of ±5ppm over all conditions
including temperature, voltage, and aging. The design is extremely rugged, has achieved automotive
AEC-Q100 certification, and can sustain extreme levels of mechanical shock and variable frequency
vibration. Because of the extremely small size of the MEMS resonator, the device is packaged in a small
8-pin, 150-mil SO—something unattainable with tuning fork crystals.
