Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct voltage, package, and tolerance specifications. Confirm RoHS compliance status and lead-free requirements prior to ordering. Check for any recent revisions or obsolescence notices from ILSI to avoid sourcing discontinued variants. Ensure the selected distributor provides genuine components with traceable documentation.

Oscillators Selection Notes

Select this component when a precise 28.63636 MHz reference is required for LVCMOS-compatible circuits. Consider the ±50ppm tolerance for applications where moderate frequency accuracy suffices. The wide temperature range makes it suitable for harsh environments. Evaluate board space constraints due to the small SMD footprint. Compare power consumption characteristics if battery efficiency is critical.

Oscillators Part Context

This part belongs to the ISA11 series of surface-mount oscillators from ILSI. The series is designed for cost-effective timing solutions in portable and industrial electronics. The 3FBH variant specifically denotes the 3.3V LVCMOS output type in a 4-pin SMD package. It serves as a direct replacement for older through-hole or larger surface-mount oscillators in modern miniaturized designs.

Oscillators Replacement Considerations

Direct substitutes may include other 28.63636 MHz LVCMOS oscillators from manufacturers like Epson, SiTime, or TXC, provided pinout and electrical parameters match. Verify that alternative parts support the same enable/disable functionality and operate within the -40°C to +125°C range. Ensure the replacement package size fits the existing PCB land pattern without modification.
