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

Can the 8N3DV85AC-0097CDI8 be used in a design requiring dual-frequency VCXO operation with independent control over both frequencies?
The 8N3DV85AC-0097CDI8 supports dual-frequency output via its internal architecture, enabling precise frequency synthesis for applications like telecom synchronization. However, both outputs are derived from the same reference and phase-locked loop (PLL), meaning they cannot operate completely independently without careful configuration. Engineers should verify timing alignment and jitter performance when using both outputs simultaneously in time-sensitive systems.
What are the implications of using the 8N3DV85AC-0097CDI8 in an industrial temperature range (-40°C to 85°C) with high ambient humidity?
While the 8N3DV85AC-0097CDI8 is rated for -40°C to 85°C operation and has an MSL rating of 1, prolonged exposure to high humidity during storage or assembly can compromise solder joint integrity over time. Designers should ensure proper conformal coating or encapsulation in humid environments and follow JEDEC J-STD-020 guidelines for moisture handling during PCB assembly to prevent popcorning or reliability degradation.
How does the supply voltage tolerance of the 8N3DV85AC-0097CDI8 compare to other FemtoClock NG series devices, and what risks exist if powered from a noisy 3.3V rail?
The 8N3DV85AC-0097CDI8 operates within a tight 3.135V to 3.465V range, which aligns closely with standard 3.3V logic supplies but offers less margin than some older VCXOs. On a noisy 3.3V rail, even minor transients above 3.465V can cause instability or shutdown. A low-dropout regulator (LDO) with <1% line regulation and adequate bypassing is recommended to maintain clean power and avoid clock signal corruption.
Is it possible to replace the 8N3DV85AC-0097CDI8 with a standard XO in a legacy system, and what trade-offs would this introduce?
Replacing the 8N3DV85AC-0097CDI8 with a standard oscillator eliminates tuning capability and frequency flexibility, which may be acceptable only if the system does not require precise frequency adjustment or compensation for thermal drift. However, standard XOs typically exhibit higher aging rates and worse phase noise, potentially degrading synchronization accuracy in telecom or instrumentation applications.
What configuration method is used to set the output frequencies of the 8N3DV85AC-0097CDI8, and can it be reprogrammed in the field?
The 8N3DV85AC-0097CDI8 uses internal registers configured via a serial interface (likely I²C or SPI) at startup. Once powered, the frequencies are fixed unless reconfigured by resetting the device. This allows field reprogramming during commissioning but requires access to the control interface and prevents runtime frequency switching without a microcontroller or external sequencer.
How does the current draw of the 8N3DV85AC-0097CDI8 impact power budget in battery-powered or compact embedded systems?
At 130 mA typical supply current, the 8N3DV85AC-0097CDI8 consumes significant power compared to modern low-power clocks. In battery-operated designs, this can drastically reduce operational lifetime unless duty-cycled or powered down during idle periods. Designers must evaluate whether alternative timing solutions or dynamic power management strategies can offset this consumption without sacrificing stability.
Can the 8N3DV85AC-0097CDI8 drive multiple loads or long transmission lines without signal degradation?
The 8N3DV85AC-0097CDI8 provides differential LVDS outputs capable of driving one 100 Ω terminated load directly. Driving multiple loads or long traces increases capacitive loading, risking waveform distortion and jitter accumulation. Use of AC-coupled buffers or repeaters is recommended beyond one load or when trace lengths exceed 5 cm in FR4 PCB layouts to preserve signal integrity.
What alternatives exist if the 8N3DV85AC-0097CDI8 cannot meet a tighter phase noise requirement for a wireless baseband application?
For stricter phase noise needs, consider higher-performance VCXOs from the same FemtoClock NG family (e.g., 8N3QV85 models) or migrate to OCXO-based solutions, though at increased cost and power. Alternatively, use a disciplined reference oscillator with external PLL filtering to improve effective phase noise, but verify that the total system jitter remains within specification.
Does the 8N3DV85AC-0097CDI8 support frequency ramping or fast lock acquisition required in dynamic communication protocols?
The 8N3DV85AC-0097CDI8 does not support hardware-controlled frequency ramping; it locks quickly upon power-up (typically within milliseconds), which suits most static synchronization needs. However, in protocols requiring rapid frequency hops (e.g., adaptive modulation schemes), the fixed output may not allow sufficient settling time, necessitating external frequency synthesizer coordination or a more agile timing source.
Are there known long-term reliability concerns when using the 8N3DV85AC-0097CDI8 in continuous high-temperature operation near 85°C?
Continuous operation near 85°C accelerates electromigration and dielectric stress within the IC, potentially increasing failure rates over time. While the device is qualified for industrial use, derating recommendations suggest limiting sustained temperatures above 70°C for extended life. Monitoring initial aging behavior and incorporating redundancy or periodic recalibration can mitigate risk in mission-critical deployments.
