Frequently Asked Questions
Why is a parallel 3rd overtone crystal like ABM3B-26.000MHZ-10-1-U-T used instead of a fundamental mode crystal at 26 MHz?
A 3rd overtone crystal achieves 26 MHz by vibrating at the third harmonic of its mechanical resonance, which allows thicker and more robust quartz blanks compared to fundamental mode crystals at the same frequency. The parallel 3rd overtone design in ABM3B-26.000MHZ-10-1-U-T offers better aging characteristics at 5 ppm per year and tighter ±10 ppm tolerance for stable reference clocking in RF and communication circuits.
How does the 10 µW drive level specification of ABM3B-26.000MHZ-10-1-U-T affect oscillator circuit design?
The 10 µW maximum drive level means the oscillator circuit must limit the power dissipated in the crystal to this value to avoid frequency drift, aging acceleration, or crystal damage. Designers must calculate the equivalent series resistance and oscillator gain carefully, especially in CMOS inverter oscillator topologies, to stay within the 10 µW limit while maintaining reliable start-up across the full supply voltage range.
In which wireless and communication chipset designs is a 26 MHz reference crystal like ABM3B-26.000MHZ-10-1-U-T commonly specified?
A 26 MHz reference crystal is the standard clock input for many Bluetooth, Wi-Fi, and LTE baseband chipsets from major semiconductor vendors. ABM3B-26.000MHZ-10-1-U-T with its ±10 ppm tolerance and 5 ppm/year aging suits designs where the host system relies on the crystal for both RF carrier synthesis and baseband timing, reducing the risk of frequency error accumulation over the product service life.
What lead time should procurement teams expect for ABM3B-26.000MHZ-10-1-U-T and how should they manage supply risk?
The factory lead time for ABM3B-26.000MHZ-10-1-U-T is 12 weeks. For wireless communication products with high-volume production schedules, teams should place blanket purchase orders well in advance and maintain safety stock of several thousand units to cover demand variability, as crystal component shortages can halt production lines for weeks if orders are placed only as needed.
