Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure the 3.3V supply voltage aligns with the system power rails. Confirm that the 4-SMD no-lead package dimensions fit within the available PCB footprint constraints. Cross-reference the manufacturer's datasheet for thermal and electrical specifications to ensure reliable operation under intended environmental conditions.

Oscillators Selection Notes

Select this component when a low-cost, standard-frequency oscillator with LVCMOS outputs is required. The 11.392 MHz frequency is suitable for baud rate generation in serial communications. Consider the power-down feature if battery life or thermal management is a priority. Verify that the operating temperature range meets the application's environmental demands. Compare against other Mercury series oscillators for pinout and size compatibility.

Oscillators Part Context

This part belongs to the 3QHTF21 series of standard XO (Crystal Oscillator) products from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down control feature. This model is part of Mercury's broader portfolio of frequency control solutions, which includes crystals and differential oscillators.

Oscillators Replacement Considerations

Direct substitutes may include other 3QHTF21 series variants with identical pinouts and functionality but different frequencies. Check for equivalent LVCMOS oscillators from other manufacturers with matching 4-SMD no-lead packages and 3.3V operation. Ensure the replacement supports the same standby control mechanism.
