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 SIT9365AC-4E3-33E74.175824 be used directly with a 3.3V HCSL receiver, or is additional termination required?
The SIT9365AC-4E3-33E74.175824 is specified for a 3.3V HCSL output, so it should be matched to an HCSL-compatible input that follows the expected common-mode and termination scheme. In many designs, HCSL inputs require external termination at the receiver rather than the oscillator driving a high-impedance load directly. Check the receiving device datasheet for termination, biasing, and allowable input common-mode range before committing the clock tree.
What should I check when replacing a quartz oscillator with the SIT9365AC-4E3-33E74.175824 in an existing PCB footprint?
When replacing a quartz-based clock source with the SIT9365AC-4E3-33E74.175824, verify more than pin count and package size. The output topology is HCSL, the supply is 3.3V, and the enable/disable function must map cleanly to the existing control net. Also confirm trace termination, input thresholds at the destination, and whether the downstream device accepts HCSL rather than LVCMOS or LVDS.
Is the SIT9365AC-4E3-33E74.175824 suitable for PCIe or other high-speed clocking applications?
The SIT9365AC-4E3-33E74.175824 may fit applications that explicitly call for a 74.175824 MHz HCSL reference, but suitability depends on the full clocking requirements of the target interface. Many PCIe-related designs need specific frequencies, jitter performance, and output standards. Confirm the exact reference frequency, phase-noise or jitter budget, and whether the endpoint expects HCSL at 3.3V before using this part.
How does the enable/disable pin on the SIT9365AC-4E3-33E74.175824 affect startup and system power sequencing?
The SIT9365AC-4E3-33E74.175824 includes enable/disable control, which is useful when the clock must be gated during reset or low-power states. In practice, you should define the default state with pull-up or pull-down resistors so the oscillator behavior is deterministic during power ramp. Also confirm that disabling the oscillator does not leave dependent devices in an undefined state if their clock is removed abruptly.
What are the main integration risks when using the SIT9365AC-4E3-33E74.175824 with a 1.8V or 2.5V logic domain?
The SIT9365AC-4E3-33E74.175824 is a 3.3V part with HCSL output, so interfacing into lower-voltage logic domains is not a direct drop-in unless the receiving device is specified to accept that clock format. The main risks are input common-mode mismatch, termination incompatibility, and overvoltage on clock inputs. If the downstream device is lower-voltage, use an accepted level translation or choose a clock source that matches the receiver’s native input standard.
How should I evaluate frequency tolerance and temperature range for the SIT9365AC-4E3-33E74.175824 in industrial equipment?
The SIT9365AC-4E3-33E74.175824 is specified at ±50ppm over -20°C to 70°C, which is appropriate for controlled-environment systems but may not cover wider industrial or outdoor conditions. For industrial use, compare the oscillator’s total frequency error against the system’s timing margin across voltage, temperature, aging, and load conditions. If the enclosure sees temperatures outside the listed range, select a version rated for the actual operating envelope.
Can the SIT9365AC-4E3-33E74.175824 replace a SiTime SIT9365 variant with a different output type?
Not automatically. The SIT9365AC-4E3-33E74.175824 is an HCSL oscillator, so replacement compatibility depends on the original output standard, supply voltage, enable polarity, and footprint. A different SIT9365 variant may share the same family and package but still differ in output format or frequency. The design should be checked at the receiver input and not just at the mechanical footprint level.
What layout practices help preserve signal quality with the SIT9365AC-4E3-33E74.175824?
For the SIT9365AC-4E3-33E74.175824, keep the clock trace short, route it with controlled impedance where the receiving interface expects it, and place termination as required by the sink device rather than by assumption. Keep noisy switching nodes away from the oscillator supply and output path. A solid reference plane and a clean 3.3V rail help reduce coupling into the clock network.
Is the SIT9365AC-4E3-33E74.175824 a good choice for designs that need very wide temperature or long-life field deployment?
The SIT9365AC-4E3-33E74.175824 can work in fielded systems that stay within its specified temperature window and timing budget, but long-life deployment usually depends on environmental headroom. Designers should account for aging, supply variation, and the actual ambient or board temperature profile over the product’s lifetime. If the installation sees higher or broader thermal stress, a device with a wider operating range is usually a better fit.
What alternative parts should I compare against the SIT9365AC-4E3-33E74.175824 before finalizing the clock source?
When comparing alternatives to the SIT9365AC-4E3-33E74.175824, focus on the exact frequency, HCSL output compatibility, 3.3V supply, enable/disable behavior, and package dimensions. Alternatives from SiTime or other vendors may differ in startup behavior, stability, jitter, or pinout even when the nominal frequency is similar. The best substitute is the one that matches the receiver’s electrical requirements and the board’s assembly constraints, not just the same MHz value.
