Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this model when a 34.6 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage and standby feature for power-sensitive designs. The small 4-SMD package is suitable for space-constrained layouts. Verify temperature range specifications if the application involves extreme environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent packaging and electrical characteristics. The 'PD' suffix typically indicates specific packaging or handling options defined by the manufacturer. These oscillators are part of Mercury's broader portfolio of frequency control products established since 1973.

Oscillators Replacement Considerations

Direct replacements must match the 34.6 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers ensuring identical pinout and electrical parameters. Verify that any substitute supports the same standby functionality and operating temperature range.
