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 4-SMD 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 38.362 MHz clock signal is required with low power consumption capabilities. The LVCMOS output ensures direct interfacing with standard logic families without additional buffering. Consider the 1.8V operating voltage to maintain compatibility with modern low-power integrated circuits. The small package size makes it ideal for dense board layouts where space is limited.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 2.0x1.6mm SMD package. The series supports LVCMOS outputs and includes power-down functionality across different frequency options. Mercury Electronics has produced frequency control products since 1973, establishing itself as a pioneer in the crystal industry.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical pinout and package but different frequencies, such as 18QHTF21-38.680-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable. Cross-brand replacements require matching LVCMOS logic, 1.8V supply, and 4-SMD no-lead package dimensions.
