Oscillators Procurement Notes

Verify the specific suffix 'PD' indicates the power-down feature when sourcing replacements. Confirm the 1.8V operating voltage matches the target circuit design. Ensure the 4-SMD footprint aligns with the PCB layout requirements. Check manufacturer datasheets for precise tolerance and temperature range specifications before finalizing procurement.

Oscillators Selection Notes

Select this component for applications requiring a precise 48.213333 MHz reference signal. The 1.8V supply requirement suits low-power digital designs. The small 2.0x1.6 mm package is ideal for space-constrained boards. Verify that the LVCMOS output compatibility exists with the receiving logic gates or microcontrollers in the system architecture.

Oscillators Part Context

This part belongs to the Mercury 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and supply voltages. The 'PD' suffix typically denotes power-down capability. Mercury Electronics has produced frequency control products since 1973, establishing this series as a standard solution for embedded timing needs.

Oscillators Replacement Considerations

Direct substitutes include other 48.213333 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure replacement parts match the 1.8V supply and pinout configuration. Verify equivalent electrical parameters such as phase noise and stability if critical to the application.
