• Embedded system clock sources

Oscillators Procurement Notes

Verify the exact part number suffix against official Mercury Electronics documentation to ensure correct frequency and package specifications. Confirm that the 1.8V supply requirement aligns with your system design before procurement. Check for any specific ordering codes or revision differences in the manufacturer's latest catalog.

Oscillators Selection Notes

Select this component when a 21.8418 MHz clock source with LVCMOS outputs is required. Ensure the 1.8V operating voltage matches the target system's power rails. Consider the 4-SMD package size for PCB layout constraints. Verify temperature range requirements against application needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronics. The series typically offers various frequencies with standard LVCMOS outputs. The 'OE' suffix likely denotes a specific packaging or tape-and-reel configuration, though exact details require datasheet verification.

Oscillators Replacement Considerations

Direct substitutes must match the 21.8418 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package. Cross-reference with other manufacturers offering similar SMD oscillators if Mercury Electronics parts are unavailable.
