Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official documentation to confirm the exact electrical specifications and pinout configuration. Ensure that the required operating temperature range and load capacitance match the target application design constraints before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 1.8V supply voltage and LVCMOS output are required. Consider the 4-SMD no-lead package dimensions for PCB layout compatibility. Verify that the 43.4835 MHz frequency aligns with the system timing requirements and that the enable/disable feature is utilized in the circuit design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized small form factor. The 'OE' suffix likely denotes a specific packaging or testing variant defined by the manufacturer, distinguishing it from other suffixes like 'PD' found in related listings.

Oscillators Replacement Considerations

Direct substitutes must match the 43.4835 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Cross-reference with Mercury Electronics' current product catalog for updated part numbers or equivalent frequencies if minor adjustments are permissible.
