Description

Product Overview

The Q22FA1280056900 is a 32.768 kHz tuning fork crystal oscillator, typically manufactured by Seiko Epson. This frequency is the standard timebase for real-time clock (RTC) circuits, and the crystal provides the precise 2^15 Hz reference needed for timekeeping applications.

Features

  • 32.768 kHz standard RTC frequency (2^15 Hz)
  • Tuning fork crystal for low-power oscillation
  • High frequency stability for timekeeping accuracy
  • Compact surface-mount or cylinder package
  • Industry-standard pinout and specifications

Applications

  • Real-time clock (RTC) timebase
  • Watch and wearable timekeeping
  • Embedded system RTC reference
  • Battery-backed timekeeping circuits

The Q22FA1280056900 is a 32.768 kHz tuning fork crystal oscillator, typically from Seiko Epson, providing the standard 2^15 Hz timebase frequency for real-time clock circuits. With +/-20 ppm typical frequency tolerance and 12.5 pF load capacitance, it enables timekeeping accuracy of approximately +/-1 minute per year in RTC applications. The crystal is designed for low-power oscillation, making it suitable for battery-backed timekeeping in embedded systems, wearables, and consumer electronics.

The Q22FA1280056900 is a tuning fork crystal operating at 32.768 kHz, which equals 2^15 Hz. The tuning fork geometry uses a bar-shaped quartz element that vibrates in a flexural (bending) mode. This mode provides a low-frequency oscillation with excellent frequency stability and very low power consumption. The quartz element is cut at a specific angle relative to the crystal axes to minimize the temperature coefficient at room temperature, resulting in a parabolic frequency-temperature curve with the turnover point near 25 deg C. The 12.5 pF load capacitance specification determines the external capacitor values needed in the Pierce oscillator circuit typically used with RTC ICs.
