• Utilizes LVCMOS output logic for digital interface compatibility
• Housed in a 4-SMD, No Lead surface-mount package

Oscillators Applications

• General electronic timing circuits
• Digital signal processing systems
• Communication equipment clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Ensure the 7.0x5.0mm footprint matches the PCB layout design to avoid mechanical interference.

Oscillators Selection Notes

Select this component when a precise 2.2222 MHz reference is required with low-power standby capabilities. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 3.3V operating voltage and the specific SMD package size during the initial hardware design phase to ensure proper board space allocation.

Oscillators Part Context

This part belongs to the 3QHTF57 series from Mercury Electronics, which offers various frequencies within the same physical form factor. The series is characterized by its small 7.0x5.0mm footprint and support for power-down modes, making it suitable for portable or power-sensitive applications requiring stable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 2.2222 MHz frequency, 3.3V LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering equivalent timing solutions in the same package style.
