Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and electrical characteristics match the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check for any specific environmental or reliability certifications required for the application.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for digital applications. The 1.8V operation makes it suitable for modern low-power systems. The LVCMOS output simplifies integration with microcontrollers and FPGAs. Consider the operating temperature range and stability requirements relative to the specific application environment before finalizing the selection.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a 2.0x1.6 mm SMD package. The manufacturer specializes in quartz crystals and oscillators, providing timing solutions for consumer electronics and industrial applications. This specific model provides a fixed frequency output for precise timing needs.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with different frequencies, such as 18QHTF21-96.768-PD or 18QHTF21-50.2067-PD, provided the frequency difference is acceptable. Cross-brand replacements must match the 4-SMD no-lead footprint, 1.8V supply, and LVCMOS output characteristics.
