Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct configuration. Confirm that the 1.8V supply requirement aligns with the target system design. Check the datasheet for precise electrical characteristics including load capacitance and drive level requirements before integration into final products.

Selection Notes

Select this component when a stable 86.99 MHz reference is required for LVCMOS compatible circuits. Ensure the application supports the 1.8V operating voltage range. Consider the physical dimensions of the 4-SMD package during layout planning. Verify temperature stability requirements against the standard oscillator specifications provided in the official data sheet.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The -OE suffix typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer. This family provides reliable timing solutions for general electronic applications requiring precise frequency generation.

Replacement Considerations

Direct substitutes must match the 86.99 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify pinout compatibility for the 4-SMD No Lead package. Cross-reference with other manufacturers offering similar small form factor oscillators if availability is constrained.
