Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 2 MHz clock signal is needed in space-constrained designs. The LVCMOS output ensures compatibility with standard digital logic families. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the 1.8V operating voltage to ensure proper interfacing with downstream logic circuits.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages, typically utilizing a 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same family.

Oscillators Replacement Considerations

Direct substitutes may include other 2 MHz LVCMOS oscillators in a 2.0x1.6 mm SMD package with 1.8V operation and power-down functionality. Verify pinout compatibility and electrical characteristics such as phase noise and jitter before substitution.
