RTC and 32.768kHz Clocks
32.768kHz oscillators with a wide range of current (<1µA to<400µA) and temperature stability (up to -40 to 105°C) offer designers opportunity to match requirements closely. -40 to 85°C temperature range AT-Cut quartz solutions achieve <50ppm over -40 to 85°C; IC's with EEPROM and Tuning fork or AT-Cut crystals achieve stabilities ≤5ppm.
