Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable and within the specified operating range to ensure reliable oscillator performance. Check for any specific handling instructions related to the no-lead SMD package during assembly.

Oscillators Selection Notes

Select this component when a precise 14.436 MHz clock source is required in a minimal footprint. The 1.8V supply requirement makes it suitable for modern low-power systems. Ensure the application can accommodate the LVCMOS logic levels and that the power-down feature aligns with system sleep cycle requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a 2.0x1.6 mm package. The series is designed for applications requiring small size and low power consumption. Other variants in this family share similar electrical characteristics but differ in output frequency and potentially pin configuration.

Oscillators Replacement Considerations

Direct substitutes must match the 14.436 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal specifications before replacing.
