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 enable/disable pin configuration matches your control logic to manage power states effectively during operation.

Selection Notes

Select this component when a low-voltage LVCMOS interface is required alongside power-saving capabilities. The enable/disable feature makes it suitable for battery-operated devices or systems requiring dynamic clock gating. Verify that the 4-SMD footprint fits within your PCB layout constraints and thermal requirements.

Part Context

This part belongs to the 18QHTF series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, all sharing a common small-form-factor SMD package. These components are designed for general-purpose timing applications where size and power efficiency are critical factors.

Replacement Considerations

Direct substitutes include other 10.135 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation and enable pins. Verify pinout compatibility and electrical specifications such as jitter and phase noise before substitution.
