Oscillators 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 target circuit's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 25.000 MHz timing source is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable pin if dynamic power saving is necessary. The small 2.0x1.6 mm package is ideal for space-constrained portable or high-density electronic designs requiring reliable quartz-based frequency control.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies and voltage options, including 1.8V and 2.5V variants. These components are widely used in consumer electronics and industrial applications where stable clock signals are critical for synchronous data transmission and processing operations.

Oscillators Replacement Considerations

Direct substitutes include other 25.000 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as phase noise and jitter before substitution.
