Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current documentation to ensure correct pinout and electrical specifications. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any recent updates to the datasheet regarding thermal or mechanical constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The enable/disable feature makes it suitable for battery-powered devices where power conservation is critical. Ensure the host circuit supports LVCMOS logic levels and can handle the 21.53 MHz frequency without additional buffering if necessary.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 2.0x1.6 mm footprint. The 'OE' suffix likely denotes specific packaging or testing configurations as defined by the manufacturer's internal coding standards for this product line.

Oscillators Replacement Considerations

Direct substitutes must match the 21.53 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify that alternative components support the same enable/disable functionality and meet identical electrical performance criteria for seamless integration.
