Frequently Asked Questions
How does the 10 ppm frequency tolerance of ABM3B-25.000MHZ-10-1-U-T affect its suitability for 25 MHz Ethernet PHY reference clock applications?
The ABM3B-25.000MHZ-10-1-U-T provides 10 ppm frequency tolerance at 25 MHz, which equates to a maximum frequency deviation of 250 Hz from the nominal. This accuracy level meets the IEEE 802.3 specification requiring Ethernet reference clocks within 100 ppm, making ABM3B-25.000MHZ-10-1-U-T a suitable low-cost option for 10/100 Mbps Ethernet PHY clock inputs.
What is the significance of the 3rd overtone parallel resonance mode of ABM3B-25.000MHZ-10-1-U-T compared to fundamental mode crystals?
ABM3B-25.000MHZ-10-1-U-T operates in parallel 3rd overtone mode, which uses the third harmonic resonance of the crystal blank to achieve 25 MHz without the physical thickness limitations of a fundamental-mode crystal at high frequencies. This requires the oscillator circuit to include a tank inductor tuned to suppress the fundamental and 1st overtone, but provides better phase noise and mechanical stability than a thin fundamental-mode crystal at the same frequency.
How does the 5 ppm/year aging specification of ABM3B-25.000MHZ-10-1-U-T impact frequency accuracy over a 10-year product lifespan?
With an aging rate of 5 ppm/first year, the ABM3B-25.000MHZ-10-1-U-T may accumulate up to approximately 50 ppm of frequency drift over a 10-year operational life, added to the initial 10 ppm tolerance. For applications with strict long-term timing budgets, designers should account for total accumulated error of 60 ppm or more and consider whether periodic calibration or TCXO alternatives are warranted.
What procurement lead time should engineers plan for when designing ABM3B-25.000MHZ-10-1-U-T into a new product requiring volume production?
ABM3B-25.000MHZ-10-1-U-T has a published factory lead time of 12 weeks, which is longer than commodity passives. Engineers planning volume production should order 12 to 16 weeks in advance or secure buffer stock of at least 1000 to 5000 units to prevent supply shortages during product launch. The tape and reel packaging format supports high-volume pick-and-place placement without minimum quantity restrictions per reel.
