Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure that the 1.8V supply voltage aligns with the target circuit's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to guarantee signal integrity and proper operation within the application environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standby feature for power conservation. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Ensure the application can accommodate the specific 45.714285 MHz frequency requirement and LVCMOS interface characteristics provided by this oscillator model.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 4-SMD no-lead package. The series provides options for different supply voltages and output types, but this specific suffix indicates the 1.8V LVCMOS variant with standby capability.

Oscillators Replacement Considerations

Direct substitutes must match the 45.714285 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical parameters such as phase noise and jitter if available in official datasheets.
