Oscillators Procurement Notes

Verify the specific supply voltage requirements against the target circuit design, as the series supports multiple voltage options including 3.3V. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a fixed frequency of 171.925 MHz is required for synchronous data transmission or processing. Consider the LVCMOS output type if interfacing directly with standard digital logic families without additional buffering. Evaluate the -40°C to 85°C temperature range against the environmental conditions of the end application to ensure long-term reliability and frequency stability under thermal stress.

Oscillators Part Context

This part belongs to the 3QHTF57 series of surface-mount crystal oscillators from Mercury Electronic Ind. Co., Ltd. The series is characterized by its small form factor and robust performance in industrial settings. Similar models in the lineup offer different frequencies and voltage options, such as the 3QHTF57-2.540-OE for lower frequency applications or the 3QHTF57-54.432-OE for alternative clock speeds, all sharing the same package and basic operational characteristics.

Oscillators Replacement Considerations

Direct substitutes include other 3QHTF57 series variants with identical pinouts but different frequencies, such as 3QHTF57-1.0752-OE or 3QHTF57-181.200-OE, provided the system can tolerate the frequency difference. Cross-brand replacements require matching the 4-SMD No Lead package, LVCMOS output, and 171.925 MHz frequency precisely.
