• Compact circuit boards where small footprint is critical

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability standards to ensure component suitability for the intended application environment.

Oscillators Selection Notes

Select this component when an LVCMOS-compatible clock source is required at 19.312 MHz with strict space limitations. The 1.8V operation makes it suitable for modern low-voltage digital circuits. Consider the standby feature if power management is a priority. Compare against other models in the 18QHTF21 series for alternative frequencies or voltage levels if the specific parameters do not match the design requirements exactly.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series offers various standard frequencies with LVCMOS outputs. Mercury Electronics has a long history in quartz crystal manufacturing, providing frequency control products since 1973. This specific model represents a standard XO variant optimized for low-power, space-constrained applications.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and form factor but different frequencies, such as 18QHTF21-18.8696-PD or 18QHTF21-31.200-PD, provided the frequency difference is acceptable for the system timing requirements. Verify compatibility with existing firmware or hardware timing constraints before swapping.
