Oscillators Procurement Notes

Verify the specific suffix (OE) against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure the operating temperature range meets your environmental requirements. Cross-reference the part number with authorized distributors to avoid counterfeit components. Confirm that the 1.8V supply voltage aligns with your system design constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power efficiency is critical. Verify that the 18.55 MHz frequency matches the target application's clock requirements precisely.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on high-frequency stability in miniature packages. The series is characterized by its use of quartz crystal technology for reliable frequency generation.
