Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the operating temperature range aligns with the environmental conditions of the end application. Ensure the PCB footprint matches the 2.5x2.0mm SMD package specifications to guarantee proper soldering and mechanical stability during operation.

Oscillators Selection Notes

Select this component when a precise 77.885 MHz timing source is required within a constrained board area. The choice is driven by the need for low-power standby functionality and standard LVCMOS signaling levels. Consider the manufacturing history of Mercury Electronics as a quartz pioneer if long-term supply consistency is a priority for the production lifecycle.

Oscillators Part Context

This oscillator belongs to the 3QHTF22 series from Mercury Electronic Ind. Co., Ltd., a manufacturer established in 1973 and recognized as a pioneer in Taiwan's quartz crystal industry. The series represents standard XO solutions designed for modern electronic systems requiring reliable frequency control in small form factors.

Oscillators Replacement Considerations

Direct substitutes include other 77.885 MHz LVCMOS oscillators in 4-SMD packages with identical 3.3V supply and pinout configurations. Verify equivalent electrical parameters such as phase noise and jitter specifications to ensure functional parity without redesigning the host circuitry.
