Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

How should AX5HBF1-75.0000C be interfaced to a logic device that expects CMOS or LVDS clock levels?
AX5HBF1-75.0000C outputs HCSL, so a direct connection is only suitable when the receiving device explicitly supports HCSL signaling or has an input stage designed for it. If the target clock input expects CMOS or LVDS, check the input common-mode range, termination requirements, and logic thresholds before using AX5HBF1-75.0000C. In many designs, HCSL is paired with external termination at the receiver, and a level translation or different oscillator family may be needed if the downstream clock tree is not HCSL-compatible.
Can AX5HBF1-75.0000C be used when the system rail is not 2.5V?
AX5HBF1-75.0000C is specified for a 2.5V supply, so use it only where the local power architecture can provide a clean 2.5V rail within the oscillator’s operating limits. If the board is built around 1.8V or 3.3V clock domains, the surrounding circuitry may need a dedicated 2.5V regulator or a different oscillator option that matches the available rail. Also check startup sequencing and rail tolerance, because oscillator stability and output behavior can shift if the supply is noisy or outside the intended range.
What should be checked before replacing another 75 MHz oscillator with AX5HBF1-75.0000C?
When replacing a different 75 MHz part with AX5HBF1-75.0000C, compare the output standard, supply voltage, enable pin behavior, pinout, package size, and startup characteristics. A part that looks frequency-compatible may still fail in the board if the old device used CMOS, LVDS, or a different enable polarity. AX5HBF1-75.0000C also uses an 8-SMD, no-lead package, so footprint compatibility and land pattern alignment should be verified before swap-in qualification.
Is AX5HBF1-75.0000C appropriate for industrial equipment that runs across wide temperature ranges?
AX5HBF1-75.0000C is rated for -40°C to 85°C, which fits many industrial and embedded environments, provided the clock budget can tolerate the specified ±20ppm stability over temperature and operating conditions. For systems with tighter timing margins, long cable runs, or high fanout clock trees, include margin for supply variation, board heating, and receiver tolerance. If the application is exposed to harsher thermal cycling or extended high-temperature operation, validate frequency drift and startup behavior in the actual enclosure.
How does the enable/disable function of AX5HBF1-75.0000C affect power sequencing and low-power modes?
AX5HBF1-75.0000C includes an enable/disable function, which makes it useful in designs that gate clocks during standby or controlled startup. The practical check is whether the downstream logic can tolerate clock removal and reappearance without corrupting state or causing PLL unlock events. In power-managed systems, confirm the disable pin’s default state, timing relative to rail ramp-up, and the oscillator’s disable current, since AX5HBF1-75.0000C still draws current even when disabled.
What termination or routing practices are typically needed with AX5HBF1-75.0000C HCSL output?
AX5HBF1-75.0000C uses HCSL output signaling, so the receiver-side termination network and trace routing should be planned around that interface rather than treated like a generic single-ended clock. Keep the clock path short, controlled impedance, and referenced to a quiet return path. If the receiving device has integrated HCSL termination, follow that input’s recommended layout; if not, confirm the external resistor arrangement and allowable biasing so the oscillator sees the intended load.
Can AX5HBF1-75.0000C be used as a drop-in substitute for Abracon or non-Abracon 75 MHz oscillators?
AX5HBF1-75.0000C may be a practical substitute only when the original part matches on frequency, supply voltage, output type, enable behavior, package dimensions, and pin assignment. Even within 75 MHz oscillators, the electrical interface can differ enough to change receiver biasing or startup timing. For a true replacement, compare the full system-level clock requirements rather than relying on frequency alone, and verify the board’s solder footprint against the 8-SMD no-lead package used by AX5HBF1-75.0000C.
What reliability checks make sense before using AX5HBF1-75.0000C in a long-life design?
For long-life use, AX5HBF1-75.0000C should be checked in the context of supply noise, thermal cycling, and mechanical stress on the 8-SMD no-lead package. Since oscillator performance can be affected by PCB power integrity and local heating, validate start-up across temperature extremes and under worst-case load. It also helps to confirm moisture-handling and assembly processes, because AX5HBF1-75.0000C is MSL 1, which simplifies storage but does not remove the need for proper reflow profiling and board-level qualification.
What design risks come up if AX5HBF1-75.0000C is used in a clock tree with tight jitter or frequency budget?
AX5HBF1-75.0000C provides a 75 MHz reference with ±20ppm stability, which is often sufficient for many digital systems, but the downstream jitter and phase-noise tolerance still depend on the receiver and any PLLs or serializers fed by the clock. If the clock tree has narrow timing margins, verify that the oscillator’s output format and stability align with the receiver’s capture requirements over temperature and supply variation. In borderline cases, measure the assembled system rather than assuming the nominal frequency spec alone will cover all timing error sources.
What should be considered before using AX5HBF1-75.0000C in a compact PCB layout?
AX5HBF1-75.0000C is packaged in a 5.00mm x 3.20mm, 1.50mm-high 8-SMD no-lead body, so layout decisions should account for pad geometry, nearby decoupling, and clock trace escape routing. In dense boards, the main risk is not the package size itself but whether the supply pin can be bypassed cleanly and the HCSL path can remain short and well controlled. Confirm that the footprint matches the manufacturer land pattern and that adjacent components do not create assembly or rework issues around AX5HBF1-75.0000C.
