Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your power architecture. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Cross-reference the datasheet for any specific handling or soldering recommendations provided by Mercury Electronics to ensure reliable assembly and long-term performance stability.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required for 85.3 MHz applications. Consider the small 2.0x1.6mm footprint if board space is limited. Verify that the enable pin feature is necessary for power management strategies. Compare against other frequencies in the QHTF21 series if different timing speeds are needed while maintaining the same package and electrical characteristics.

Part Context

This part belongs to the QHTF21 series of surface-mount oscillators from Mercury Electronic Ind Co., Ltd. The series offers various frequencies and voltage options, including 3.3V variants like the 3QHTF21 model. Mercury Electronics is a established manufacturer of quartz crystals and frequency control products, providing standardized oscillator solutions for diverse electronic industries.

Replacement Considerations

Direct substitutes may include other 85.3 MHz LVCMOS oscillators in a 4-SMD no-lead package with 1.8V operation. Verify pinout compatibility and electrical specifications carefully. Alternative packages such as 6-SMD or larger footprints may require PCB redesign. Check datasheets for equivalent parts from other manufacturers offering similar form factors and performance metrics.
