Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the small 2.0x1.6mm footprint for space-constrained designs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 1.8V LVCMOS format. The series provides consistent packaging and electrical characteristics across different frequency options, simplifying inventory management for multi-frequency designs.

Oscillators Replacement Considerations

Direct replacements must match the 1.8V LVCMOS specification and 4-SMD no-lead package. Verify equivalent frequency accuracy and phase noise specifications. Cross-reference pinout compatibility to ensure seamless integration without PCB modifications.
