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 SIT3907AC-CF133NM-100.000000Y be used directly in a 3.3 V FPGA or MCU clock input?
Yes, SIT3907AC-CF133NM-100.000000Y provides an LVCMOS/LVTTL output at 3.3 V, so it can usually drive a compatible clock input directly. Check the receiving device’s VIH/VIL thresholds, allowed clock frequency, and input pin type. For high-speed or sensitive inputs, verify trace loading and keep the clock route short with a solid return path.
What should I check before replacing a quartz oscillator with SIT3907AC-CF133NM-100.000000Y?
With SIT3907AC-CF133NM-100.000000Y, the main checks are supply voltage, pinout, output type, startup behavior, and the clock tolerance your design expects. A MEMS DCXO can behave differently from a quartz XO in phase noise, jitter, and startup characteristics, so a drop-in replacement should be validated against the downstream device’s clock margin and any timing-sensitive interfaces.
Is SIT3907AC-CF133NM-100.000000Y suitable for Ethernet, SerDes, or other jitter-sensitive links?
SIT3907AC-CF133NM-100.000000Y may work for many synchronous digital systems, but SerDes, high-speed networking, and similar links often have tighter jitter and phase-noise budgets than general-purpose logic clocks. Confirm the full clock specification of the target PHY or transceiver, including RMS jitter, period jitter, and allowed reference-clock accuracy, before using this part in those paths.
Can SIT3907AC-CF133NM-100.000000Y be used in industrial equipment running from -20°C to 70°C?
SIT3907AC-CF133NM-100.000000Y is specified for -20°C to 70°C, so it fits controlled industrial environments that stay inside that range. For sealed enclosures, outdoor systems, or equipment with elevated internal temperatures, include derating for board hotspots, airflow limits, and long-term frequency drift over temperature and aging.
What are the practical design risks when routing SIT3907AC-CF133NM-100.000000Y on a mixed-signal board?
SIT3907AC-CF133NM-100.000000Y should be routed like a clock source rather than a generic digital signal. Keep the trace short, avoid vias when possible, isolate it from noisy switch-mode power loops, and prevent stubs or impedance discontinuities that can create ringing. In mixed-signal systems, clock noise can couple into ADCs, RF sections, and PLL reference inputs.
Does SIT3907AC-CF133NM-100.000000Y need any special power-supply filtering?
A clean 3.3 V rail is the usual requirement for SIT3907AC-CF133NM-100.000000Y. Use local decoupling close to the device and make sure the supply is not sharing a noisy path with high-current switching loads. If the rail has significant ripple or transient dips, clock stability and startup margin can be affected.
How does SIT3907AC-CF133NM-100.000000Y compare with a standard fixed-frequency oscillator when the design needs frequency trim?
SIT3907AC-CF133NM-100.000000Y is a DCXO, so it is chosen when controlled frequency adjustment or tighter system alignment is needed compared with a fixed oscillator. If your application never uses tuning or correction, a simpler fixed XO may reduce cost and integration complexity. If the system needs compensation for board-level error, calibration, or closed-loop correction, the DCXO feature can be useful.
What replacement options should I evaluate if I need a pin-compatible alternative to SIT3907AC-CF133NM-100.000000Y?
For SIT3907AC-CF133NM-100.000000Y, the closest alternatives are other SiTime SiT3907 variants with the same package, output format, supply voltage, and frequency. If you consider non-SiTime parts, verify pinout, enable or control behavior, output drive, startup time, temperature stability, and jitter. Even when the frequency matches, the board may still need revalidation because MEMS and quartz devices do not always align electrically or timing-wise.
Is SIT3907AC-CF133NM-100.000000Y a good choice for battery-powered equipment?
SIT3907AC-CF133NM-100.000000Y draws up to 34 mA, so it is more suitable for systems with a stable power budget than for ultra-low-power designs. In battery-powered products, check average run time impact, power sequencing, and whether the clock stays enabled continuously or can be gated in sleep modes.
What should I consider if SIT3907AC-CF133NM-100.000000Y is used as a reference clock for an FPGA or SoC?
With SIT3907AC-CF133NM-100.000000Y, confirm the FPGA or SoC accepts 3.3 V LVCMOS/LVTTL input levels and that the clock pin is configured for single-ended reference use. Also check clock startup time, duty-cycle tolerance, and whether the device expects a fixed reference or can tolerate the DCXO’s tuning behavior if it is ever adjusted.
Can SIT3907AC-CF133NM-100.000000Y be a direct substitute for a 100 MHz quartz oscillator in existing layouts?
SIT3907AC-CF133NM-100.000000Y can often fit the same functional role, but it is not automatically a direct substitute. Compare package footprint, pad arrangement, enable pin needs, output edge behavior, and timing margin at the receiving IC. A board that works with a quartz XO may still need signal-integrity validation with a MEMS oscillator.
What reliability checks make sense for SIT3907AC-CF133NM-100.000000Y in long-life equipment?
For SIT3907AC-CF133NM-100.000000Y, common reliability checks include thermal cycling across the actual enclosure range, power-supply transients, vibration if the product is mobile, and aging tolerance in the system clock budget. Because it is a MEMS-based oscillator, qualification should focus on the full operating environment and the downstream impact of small frequency shifts over time.
